Слайд 1 Morphemes
Classification
of Morphemes
Слайд 2Words consist of morphemes. The term 'morpheme' is derived from
Greek morphe — 'form' + -erne.
The Greek suffix -erne
has been adopted by linguists to denote the smallest unit (cf. phoneme, sememe).
Слайд 3Morphemes occur in speech only as constituent parts of words
but not independently. Morphemes may have different phonetic shapes
Слайд 4In the word-cluster please, pleasing, pleasure, pleasant the root morpheme
is represented by the phonetic shapes:
[pli:z-] in please, pleasing;
[ple3-] in pleasure;
[plez-] in pleasant.
Слайд 5Root-morphemes are the lexical nucleus of words.
For example, in
the words remake, glassful, disorder the root-morphemes -make, glass- and
-order are understood as the lexical centres of the words
Слайд 6Non-root morphemes include inflectional morphemes and affixational morphemes . Inflections
carry only grammatical meaning and are thus relevant only for
the formation of word-forms, whereas affixes are relevant for building various types of stems'.
Слайд 7A prefix is a derivational morpheme preceding the root-morpheme and
modifying its meaning (pronounce — mis-pronounce, safe — un-safe).
Слайд 8 A suffix is a derivational morpheme following the
root and forming a new derivative in a different part
of speech or a different word class (cf. -en, -y, -less heart-en, heart-y,heart-less).
Слайд 91) Free morpheme is defined as one that coincides with
the stem or a word form. For example, the root-morpheme
friend- of the noun friendship is naturally qualified as a free morpheme because it coincides with one of the forms of the word friend.
Слайд 102) Bound morpheme occurs only as a constituent part of
a word. Affixes are bound morphemes for they always make
part of a word. For example, the suffixes -ness, -ship, -ize in the words darkness, friendship, to activize, the prefixes im-, dis-, de- in the words impolite, to demobilize.
Слайд 113) Semi-bound (semi-free) morphemes are morphemes that can function in
a morphemic sequence both as an affix and as a
free morpheme. For example, the morphemes well and half on the one hand occur as free morphemes that coincide with the stem and the word-form in the utterances to sleep well, half an hour, on the other hand well and half occur as bound morphemes in the words well-known, half-done.
