InflectionIn linguistic morphology, inflection (or inflexion) is a process of word formation in which a word is modified to express different such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as declension.
Semitic rootThe roots of verbs and most nouns in the Semitic languages are characterized as a sequence of consonants or "radicals" (hence the term consonantal root). Such abstract consonantal roots are used in the formation of actual words by adding the vowels and non-root consonants (or "transfixes") which go with a particular morphological category around the root consonants, in an appropriate way, generally following specific patterns.
ApophonyIn linguistics, apophony (also known as ablaut, (vowel) gradation, (vowel) mutation, alternation, internal modification, stem modification, stem alternation, replacive morphology, stem mutation, internal inflection etc.) is any alternation within a word that indicates grammatical information (often inflectional). Apophony is exemplified in English as the internal vowel alternations that produce such related words as sng, sng, sng, sng bnd, bnd bld, bld brd, brd dm, dm fd, fd l, l rse, rse, rsen wve, wve ft, ft gse, gse tth, tth The difference in these vowels marks variously a difference in tense or aspect (e.
ReduplicationIn linguistics, reduplication is a morphological process in which the root or stem of a word (or part of it) or even the whole word is repeated exactly or with a slight change. The classic observation on the semantics of reduplication is Edward Sapir's: "generally employed, with self-evident symbolism, to indicate such concepts as distribution, plurality, repetition, customary activity, increase of size, added intensity, continuance." Reduplication is used in inflections to convey a grammatical function, such as plurality, intensification, etc.
