5. The concept of the morpheme and its structural
types.
The morpheme is the elementary meaningful lingual unit
built up from phonemes and used to make words. It has meaning,
but its meaning is abstract, significative, not concrete, or
nominative, as is that of the word [2, р. 12]. Morphemes constitute
the words; they do not exist outside the words. Studying the
morpheme we actually study the word: its inner structure, its
functions, and the ways it enters speech.
Stating the differences between the word and the
morpheme, we have to admit that the correlation between the
word and the morpheme is problematic. The borderlines between
the morpheme and the word are by no means rigid and there is a
set of intermediary units (half-words – half- morphemes), which
form an area of transitions between the word and the morpheme as
33
the polar phenomena. This includes the so-called ―morpheme-
like‖ functional, or auxiliary words, for example, auxiliary verbs
and adverbs, articles, particles, prepositions and conj unctions:
they are realized as isolated, separate units (their separateness
being fixed in written practice) but perform various grammatical
functions; in other words, they function like morphemes and are
dependent semantically to a greater or lesser extent. E.g..: Jack‟s,
a boy, have done.
This approach to treating various lingual units is known in
linguistics as ―a field approach‖: polar phenomena possessing the
unambiguous characteristic features of the opposed units
constitute ―the core‖, or ―the center‖ of the field, while the
intermediary phenomena combining some of the characteristics of
the poles make up ―the periphery‖ of the field; e.g.: functional
words make up the periphery of the class of words since their
functioning is close to the functioning of morphemes.
When studying morphemes, we should distinguish
morphemes as generalized lingual units from their concrete
manifestations, or variants in specific textual environments;
variants of morphemes are called ―allo-morphs‖.
Initially, the so-called allo-emic theory was developed in
phonetics: in phonetics, phonemes, as the generalized, invariant
phonological units, are distinguished from their concrete
realizations, the allophones. For example, one phoneme is
pronounced in a different way in differe nt environments, e.g.: you
[ju:] – you know [ju]; in Russian, vowels are also pronounced in a
different way in stressed and unstressed syllables, e.g.: дом –
домой. The same applies to the morpheme, which is a generalized
unit, an invariant, and may be represented by different variants,
allo- morphs, in different textual environments. For example, the
morpheme of the plural, -(e)s, sounds differently after voiceless
consonants (bats), voiced consonants and vowels (rooms), and
34
after fricative and sibilant consonants (clashes). So, [s], [z], [iz],
which are united by the same meaning (the grammatical meaning
of the plural), are allo- morphs of the same morpheme, which is
represented as -(e)s in written speech.
The ―allo-emic theory‖ in the study of morphemes was
also developed within the framework of Descriptive Linguistics
by means of the so-called distributional analysis: in the first stage
of distributional analysis a syntagmatic chain of lingual units is
divided into meaningful segments, morphs, e.g.: he/ start/ed/
laugh/ing/; then the recurrent segments are analyzed in various
textual environments, and the following three types of distribution
are established: contrastive distribution, non-contrastive
