The word copula originates from the Latin Noun for a "link or tie" that connects two different things. In Linguistics , a copula is a word that is used to link the Subject of a Sentence with a Predicate (a subject Complement or an Adverbial ). Though it might not itself express any action or condition, it serves to equate (or associate) the subject with the predicate. A copula is sometimes (though not always) a Verb or a verb-like part of speech. In English Primary Education grammar courses, a copula is often called a linking verb. The term is generally used to refer to the main copular verb in the language: in the case of English, this is "to be". It can also be used to refer to all such verbs in the language: in that case, English copulas include "to be", "to become", "to get", "to feel", and "to seem". Other verbs have secondary uses as copulative verbs, as ''fall'' in "The zebra fell victim to the lion." For a complete list see: List Of English Copulas . THE COPULA IN ENGLISH Use We can identify several sub-uses of the copula:
The verb "to be" also has some non-copular uses, including:
Note that the auxiliary verb function derives from the copular function; and, depending on one's point of view, one can still interpret the verb as a copula and the following verbal form as being adjectival. Conjugation As in most . COPULAS IN OTHER LANGUAGES Languages tend to use copulas in quite different ways. Chinese In Chinese languages, both states and qualities are generally expressed with Stative Verb s with no need for a copula, e.g., "to be tired" (累 ''lèi''), "to be hungry" (饿 ''è''), "to be located at" (在 ''zài''), "to be stupid" (笨 ''bèn'') and so forth. These verbs are usually preceded by an adverb such as 很 ''hěn'' ("very") or 不 ''bù'' ("not"). Only sentences with a noun as the complement (e.g. "this is my sister") use the verb "to be": 是 ''shì''. This is used frequently: for example, instead of having a verb meaning "to be Chinese", the usual expression is "to be a Chinese person", using 是 ''shì''. Other sentences use adjectives plus the nominaliser 的 ''de'', e.g. 这是红的 ''zhè shì hóng de'' "this is red [one ". The history of the Chinese copula 是 is a controversial subject. Before the , 是 means "straight"; in modern Chinese, 是 means "yes" as an interjection, and "correct", "right" as an adjective, implying a sense of judgement. N.B. The characters used are Simplified ones, and the transcriptions given in italics reflect Standard Mandarin pronunciation, using the Pinyin system. Japanese Japanese has copulas which would most often be translated as one of the so-called be-verbs of English. The Japanese copula has many forms, including but not limited to ''da'', ''na'', ''de'', and ''desu''. The first and last are used to Predicate sentences, while the middle two are used within sentences to modify or connect. Japanese sentences with copulas most often equate one thing with another, that is, they are of the form "A is B." Examples:
The following examples show the use of the copula as a modifier or connector.
The difference between ''da'' and ''desu'' is simple: ''desu'' is more formal and polite than ''da''. Thus, the two sentences below are identical in meaning and differ only in their politeness.
Japanese sentences may be predicated with copulas or with verbs. However, ''desu'' may not always be a predicate. In some cases, its only function is to make a sentence predicated with a Stative Verb more polite. In a sense, there are two words ''desu'' in Japanese: one is a polite copula that predicates sentences, and the other is a politeness marker added to stative verbs. However, ''da'' always functions as a predicate, so it cannot be combined with a stative verb, because sentences need only one predicate. See the examples below.

Japanese also has two verbs corresponding to English "to be": ''aru'' and ''iru''. Neither of them is a copula. ''Aru'' is used for inanimate objects, including plants, while ''iru'' is used for people and animals, though there are exceptions to this generalization. Different usages of the copula, stative verbs, and the two verbs of being are shown below.
Indo-European languages See Also: Indo-European copula
A feature of most Romance Language s is the coexistence of two different verbs meaning "to be", the main one from the Latin ''sum'', and a secondary one from '''sto'' (see Romance Copula ). The difference is that the former usually refers to essential characteristics, whilst the latter refers to states and situations, e. g. "Bob is old" versus "Bob is well". (Note that the English words just used, "essential" and "state", are also cognate with the Latin roots ''esse'' and ''stare''.) In Spanish, for example, the quite high degree of verbal Inflection , plus the existence of two copulae (''ser'' and ''estar''), means that there are 105 separate forms to express the eight of English, and one of Chinese. In certain languages there are not only two copulae but the Syntax is also changed when one is distinguishing between states or situation and essential characteristics. For example, in Irish , describing the subject's state or situation typically uses the normal VSO ordering with the verb ''bí''. The copula ''is'', which is used to state essential characteristics or equivalences, requires a change in word order so that the subject does not immediately follow the copula (see Irish Syntax ). Russian and Hungarian In languages such as ), is known generically as the Zero Copula . Note that in other tenses (sometimes in other persons besides singular third) the copula usually reappears. In Hungarian, zero copula is restricted to present tense in 3rd person singular and plural (see examples above): "Ő ember/Ők emberek — "s/he is a human"/"they are humans"; but: "(én) ember vagyok" — "I am a human", "(te) ember vagy" — "you are a human", "(mi) emberek vagyunk" — "we are humans", "(ti) emberek vagytok" — "you (all) are humans". It also reappears for stating locations: "az emberek a házban vannak" — "the people are in the house". To recycle the above examples ("Bob is old" versus "Bob is here"), Hungarian only uses a copula in the latter case (and this not only with regard to third person singular/plural) (''Itt van Róbert''), but not in the first example (''Róbert öreg''). This is to relate a subject to a more temporary condition/state taking place in ''space'' (very often in the sense of Lojban ''zvati'' — "la rabyrt. zvati ne'i le zdani" (Robert is in the house)). In Russian, the verb "быть" (''byt’'') is the infinitive of "to be". The third person singular, "есть" (''yest’'') means "is" (and, interestingly enough, it is a homonym of the infinitive "to eat"). As a copula, it can be inflected into the past ("был", ''byl''), future ("будет", ''budet''), and subjunctive ("был" or "бы", ''byl'' or ''by'') forms. A present tense ("есть", ''yest’'') exists; however, it is almost never used as a copula, but rather omitted altogether or replaced by the verb "являться" (''yavlyat'sa'') (to be in essence). Thus one can say:
But not (except for archaic effect):
The third person plural "суть" (''sut’'') ("are") is still used in some standard phrases (but since it is a homonym of the noun "essence", most native speakers do not notice it to be a verb):
Turkish ''(See also the separate article on the Turkish Copula .)'' Unlike Indo-european languages, being an extremely regular Agglutinative Language , Turkish forms its "being" not as a regular verb, rather as an auxiliary verb denoted as "i-mek" which shows its existence only through suffixes to predicates which can be nouns, adjectives or arguably conjugated verb stems. In the third person singular, just like in Hungarian or Russian Zero Copula is the case. For example:
Georgian Just like in English, the verb "to be" (''qopna'') is irregular in Georgian ; different verb roots are employed in different tenses. The roots -''ar''-, -''kn''-, -''qav''-, and -''qop''- (past participle) are used in the present tense, future tense, past tense and the perfective tenses respectively. Examples: Masc'avlebeli var Masc'avlebeli viknebi Masc'avlebeli viqavi Masc'avlebeli vqopilv Masc'avlebeli vqopili Note that in the last two examples (perfective and pluperfective) two roots are used in one verb compound. In the perfective tense, the root ''qop'' (which is the expected root for the perfective tense) is followed by the root ''ar'', which is the root for the present tense. In the pluperfective tense, again, the root ''qop'' is followed by the past tense root ''qav''. This formation is very similar to German. In German, the perfective and the pluperfective are expressed in this way: Ich bin ein Lehrer Ich war ein Lehrer Here, ''gewesen'' is the past participle of ''sein'' ("to be") in German. In both examples, just like in Georgian, this participle is used together with the present and the past forms of the verb in order to conjugate for the perfect and the pluperfect tenses. Nahuatl Nahuatl , as well as some other Amerindian Language s, has no copula. Instead of using a copula, it is possible to conjugate nouns or adjectives like verbs. Siouan languages In Siouan languages like Lakota , this is similar as in principle almost all words - according to their structure - are verbs. So, not very unlike in Lojban (see below), not only (transitive, intransitive and so-called 'stative') verbs but even nouns often behave like verbs - and do not need to have copulas. E.g. _wicasa_ - man/adult male, to-be-a-man -> wimacasa/winicasa/he wicasa (I am/you are/he is a man). Yet, there also is a verb (copula) _heca_ [he'cha (to be a such) that in most cases is used: "wicasa hemaca/henica/heca" (I am/you are/he is a man). So, in order to express that I am a doctor of profession, I have to say: "pezuta wicasa hemaca" wicha's^a hema'cha . But in order to express that I'm THE doctor (say, that had been phoned to help), I'd have to use another copula _(i)ye_ (to be the one): "pezuta wicasa (kin) miye lo" (medicine-man DEF ART I-am-the-one MALE ASSERT). In order to refer to space (e.g. Robert is in the house), various verbs are used as copula, e.g. _yankA_ (lit.: to sit) for humans, _han/he_ [haN'/he' (to stand upright) for inanimates of a certain shape. So, "Robert is in the house" could be translated as "Robert timahel yanke (yelo)", whereas "there's one restaurant next to the gas station" translates as "owotetipi wigli-oinazin kin hel isakib wanzi he". Artificial languages The Artificial Language Lojban has copula, but they are rarely used, and are sometimes viewed with distaste in the Lojban community, because all words that express a predicate can be used as verbs. The three sentences above would all have the same form in Lojban: ''la bob. bajra'', ''la bob. tolcitno'', and ''la bob. fagdirpre''. There are several different copula: ''me'' turns whatever follows the word ''me'' into a verb that means ''to be'' what it follows. For example, ''me la bob.'' means ''to be Bob.'' Another copula is ''du'', which is a verb that means all its arguments are the same thing (equal) {Link without Title} . The E-Prime language, based on English, simply avoids the issue by not having a generic copula. It requires instead a specific form such as "remains", "becomes", "lies", or "equals". Esperanto uses the copula much as in English. However, as with the rest of Esperanto grammar, there are no irregularities. The infinitive is ''esti'', and the whole conjugation is regular. In Toki Pona , if the subject is ''mi'' (I) or ''sina'' (you, sg.) there is no copula needed; otherwise, it's used ''li'' just before the verb. For example: "sina pona" (you're good), "meli li pona" ((the) woman is good). EXISTENTIAL USAGE The existential usage of "to be" is distinct from and yet, in some languages, intimately related to its copulative usage. In language as opposed to formal logic, existence is a predicate rather than a quantifier, and the passage from copulative to existential usage can be subtle. For example:
Other languages prefer to keep the existential usage entirely separate from the copula. Swedish, for example, reserves ''vara'' for the copula, keeping ''bli'' (to become) and ''finnas'' (to be found) for becoming and existing, respectively.
In and Existence . COPULA AS SUBSET RELATOR From one perspective, the copula always relates two things as subsets. Take the following examples: #''John is a doctor.'' #''John and Mary are doctors.'' #''Doctors are educated.'' #''Mary is running.'' #''Running is fun.'' Example 1 includes John in the set of all doctors. Example 2 includes John and Mary both in the set of all doctors. Example 3 includes the set of doctors in the set of those who are educated. Example 4 is different. Example 4 includes Mary's State at the time of utterance in the Set Of States Consistent With Running . Example 5 then includes the set of states consistent with running in the set of states consistent with fun. |
