So the verb ‘bequeath’, as a less-frequent verb, has a simple conjugation: ‘I bequeath’, ‘you bequeath’, ‘she bequeaths’, ‘we bequeath’ and ‘everyone bequeaths’ (this general principle is known as Zipf’s Law). But the common verb ‘to be’, is irregular, as in ‘I am’, ‘you are’, ‘he is’, ‘we are’ and ‘they are’. Both functional pressure and information transfer requirements optimise language for better communication.
