Besides the synthetical and analytical means of building word forms in Modern English, there is yet another way of building them which stands quite apart and is found in a very limited number of cases only. By a suppletive formation we mean building a form of a word from an altogether different stem. Examples in point are, the verb go, with its past tense went; the personal pronoun I, with its objective case form me, the adjective good with its comparative degree form better, and a few more. We consider, for instance, go and went as, in a way, two forms of one word, because in the vast majority of verbs the past tense is derived from the same stem as the present or infinitive, e. g. live — lived, speak — spoke, etc. It is against this background that the units go and went come to be considered as forms of one word, formed from different stems. In the morphological system of Modern English suppletive formations are a very insignificant element, but they concern a few very widely used words among adjectives, pronouns, and verbs. Such, then, are the means of deriving the forms of words in Modern English. We shall have to ascertain the exact meaning and function of each of them as we proceed on our survey of the parts of speech.
