12. Synthetical and analytical grammatical forms.

The means employed for building up member-forms of categorial oppositions are traditionally divided into synthetical and analytical; accordingly, the grammatical forms themselves are classed into synthetical and analytical, too.

Synthetical grammatical forms are realised by the inner morphemic composition of the word, while analytical grammatical forms are built up by a combination of at least two words, one of which is a grammatical auxiliary (word-morpheme), and the other, a word of "substantial" meaning. Synthetical grammatical forms are based on inner inflexion, outer inflexion, and suppletivity; hence, the forms are referred to as inner-inflexional, outer-inflexional, and suppletive.

Inner inflexion, or phonemic (vowel) interchange, is not productive in modern Indo-European languages, but it is peculiarly employed in some of their basic, most ancient lexemic elements. By this feature, the whole family of Indo-European languages is identified in linguistics as typologically "inflexional".

Inner inflexion (grammatical "infixation", see above) is used in English in irregular verbs (the bulk of them belong to the Germanic strong verbs) for the formation of the past indefinite and past participle; besides, it is used in a few nouns for the formation of the plural. Since the corresponding oppositions of forms are based on phonemic interchange, the initial paradigmatic form of each lexeme should also be considered as inflexional. Cf.: take — took — taken, drive — drove — driven, keep — kept — kept, etc.; man — men, brother — brethren, etc.

Suppletivity, like inner inflexion, is not productive as a purely morphological type of form. It is based on the correlation of different roots as a means of paradigmatic differentiation. In other words, it consists in the grammatical interchange of word roots, and this, as we pointed out in the foregoing chapter, unites it in principle with inner inflexion (or, rather, makes the latter into a specific variety of the former).

Suppletivity is used in the forms of the verbs be and go, in the irregular forms of the degrees of comparison, in some forms of personal pronouns. Cf.: be — am — are — is — was — were; go — went; good — better; bad — worse; much — more; little — less; I — me; we — us; she — her.

As for analytical forms which are so typical of modern English that they have long made this language into the "canonised" representative of lingual analytism, they deserve some special comment on their substance.

The traditional view of the analytical morphological form recognises two lexemic parts in it, stating that it presents a combination of an auxiliary word with a basic word. However, there is a tendency with some linguists to recognise as analytical not all such grammatically significant combinations, but only those of them that are "grammatically idiomatic", i.e. whose relevant grammatical meaning is not immediately dependent on the meanings of their component elements taken apart. Considered in this light, the form of the verbal perfect where the auxiliary "have" has utterly lost its original meaning of possession, is interpreted as the most standard and indisputable analytical form 'in English morphology. Its opposite is seen in the analytical degrees of comparison which, according to the cited interpretation, come very near to free combinations of words by their lack of "idiomatism" in the above sense.
