7. The morphemic and derivational level of analysis of the word structure. Main units of word-formation. Affixation as a means of nomination in modern English

Morphemic analysis aims at determining the morphemic (morphological) structure of a word, i.e. the aim is to split the word into morphemes and state their number, types and the pattern of arrangement. The basic unit of morphemic analysis is the morpheme.

In segmenting words into morphemes, we use the method of Immediate and Unltimate Constituents. At each stage of the analysis, a word is broken down into two meaningful parts (ICs, i.e. Immediate Constituents). At the next stage, each IC is broken down into two smaller meaningful elements. The analysis is completed when we get indivisible constituents, i.e. Ultimate Constituents, or morphs, which represent morphemes in concrete words,

Friend-, -ly, -ness are indivisible into smaller meaningful units, so they are Ultimate Constituents (morphs) and the word friendliness consists of 3 morphemes: friend-+-li+-ness.

There are two structural types of words at the morphemic level of analysis: monomorphic (non-segmentable, indivisible) and polymorphic words (segmentable, divisible). The former consist only of a root morpheme, e.g. cat, give, soon, blue, oh, three. The latter consist of two or more morphemes, e.g. disagreeableness is a polymorphic word which consists of four morphemes, one root and three affixes: dis- + -agree- + -able + -ness. The morphemic structure is Pr + R + Sf1 + Sf2.

The aim of derivational analysis is to determine the derivational structure of a word, i.e. to state the derivational pattern after which it is built and the derivational base (the source of derivation).

Traditionally, the basic units of derivational analysis are: the derived word (the derivative), the derivational base, the derivational pattern, the derivational affix.

The derivational base is the source of a derived word, i.e. a stem, a word-form, a word-group (sometimes even a sentence) which motivates the derivative semantically and on which the latter is based structurally,

e.g. in dutifully the base is dutiful-, which is a stem;

in unsmiling it is the word-form smiling (participle I) ;

in blue-eyed it is the word-group blue eye.

In affixation, derivational affixes are added to derivational bases to build new words, i.e. derivatives. They repattern the bases, changing them structurally and semantically. They also mark derivational relations between words,

e.g. in encouragement en- and -ment are derivational affixes: a prefix and a suffix; they are used to build the word encouragement: (en- + courage) + -ment.

They also mark the derivational relations between courage and encourage, encourage and encouragement.

A derivational pattern is a scheme (a formula) describing the structure of derived words already existing in the language and after which new words may be built,

e.g. the pattern of friendliness is a+ -ness- → N, i.e. an adjective stem + the noun-forming suffix -ness.

Derivationally, all words fall into two classes: simple (non-derived) words and derivatives. Simple words are those that are non-motivated semantically and independent of other linguistic units structurally, e.g. boy, run, quiet, receive, etc. Derived words are motivated structurally and semantically by other linguistic units, e.g. to spam, spamming, spammer, anti-spamming are motivated by spam.

Each derived word is characterized by a certain derivational structure. In traditional linguistics, the derivational structure is viewed as a binary entity, reflecting the relationship between derivational bases and derivatives and consisting of a stem and a derivational affix,

e.g. the structure of nationalization is nationaliz- + -ation

(described by the formula, or pattern  v + -ation → N).

But there is a different point of view. In modern W-F, the derivational structure of a word is defined as a finite set of derivational steps necessary to produce (build) the derived word,

e.g.  [(nation + -al) + -ize] +  -ation.

To describe derivational structures and derivational relations, it is convenient to use the relator language and a system of oriented graphs. In this language, a word is generated by joining relators to the amorphous root O. Thus, R1O describes the structure of a simple verb (cut, permiate); R2O shows the structure of a simple noun (friend, nation); R3O is a simple adjective (small, gregarious) and R4O is a simple adverb (then, late).

e.g. The derivational structure of nationalization is described by the R-formula R2R1R3R2O; the R-formula of unemployment is R2R2R1O (employ → employment → unemployment).

In oriented graphs, a branch slanting left and down "/" correspond to R1; a vertical branch "I" corresponds to R2; a branch slanting right and down "\" to R3, and a horizontal right branch to R4.

Words whose derivational structures can be described by one R-formula are called monostructural, e.g. dutifulness, encouragement ; words whose derivational structures can be described by two (or more) R-formulas are polystructural,

e.g. disagreement  R2R2R1O / R2R1R1O

(agree → disagree → disagreement  R2R1R1O or

agree → agreement → disagreement  R2R2R1O)

There are complex units of word-formation. They are derivational clusters and derivational sets.

A derivational cluster is a group of words that have the same root and are derivationally related. The structure of a cluster can be shown with the help of a graph,

Affixation is formation of words by adding derivational affixes to derivational bases. Affixation is devided into prefixation and suffixation,

e.g. the following prefixes and suffixes are used to build words with negative or opposite meanings: un-, non-, a-, contra-, counter-, de-, dis-, in-, mis-, -less, e.g. non-toxic.
