The similarity of words between languages is ''not'' enough to demonstrate that the words are related to each other, in much the same way that facial resemblance does not determine whether two people are genetically related. Over the course of hundreds and thousands of years, words may change their sound completely. Thus, for example, English ''five'' and Sanskrit ''pança'' are cognates, while English ''over'' and Hebrew ''a'var'' are not, and neither are English ''dog'' and Mbabaram ''dog''. Contrast this with False Friend s, which frequently ''are'' cognate.
