SUFFIX An AFFIX added at the end of a WORD, BASE, or ROOT to form a new word: -ness added to dark to form darkness; -al added to leg to form legal. Two distinctions are usually made: (1) Between a derivational suffix proper, such as -ness and -al, which creates derivative words, and an inflectional ending, such as -s added to form the plurals of nouns, which changes the inflection of a word. (2) Between a productive suffix, which actively forms words (-ness: darkness, newness, quaintness, wordiness) and a non-productive suffix, which does not (-ledge: knowledge). There is a continuum from the highly through the mildly and rarely productive to the dormant and dead, and usage can vary according to time and place: the suffix -y has generally been added to vernacular nouns to form ADJECTIVES (ease/easy, oil/oily, rain/rainy) with some disyllabic bases (paper/papery, powder/powdery). In the 20c, however, -y has increasingly been added casually and often for nonce purposes to longer bases (sometimes with idiosyncratic or debatable spellings), including compounds and classical words: chocolat(e)y, drybiscuity, gardeny, linguisticky, statusy, teenagey, uppercrusty.

Origins

In 1882, the philologist Walter W. Skeat noted: ‘The number of suffixes in MODERN ENGLISH is so great, and the forms of several, especially in words derived through the FRENCH from LATIN, are so variable that an attempt to exhibit them all would tend to confusion’ (Etymological Dictionary of the English Language). The diversity of the backgrounds from which the suffixes of English have been drawn, the different periods in which they have entered the language, and the different processes involved all contribute to the complexity of the subject. Most suffixes, however, fall into one of three groups:

1. Vernacular.

Suffixes in the main from OLD ENGLISH and other GERMANIC LANGUAGES: -ish as in childish is from Old English an is cognate with GERMAN -isch as in kindisch.

2. Romance.

Suffixes that have come especially from Old French and Latin: -al as in legal and natural derives either directly or through Old French from Latin -alis as in legalis and naturalis, and is cognate with the Modern French forms -al in légal and -el in naturel.

3. Greek.

Suffixes that have come mainly through NEO-LATIN and French: -oid as in anthropoid and steroid is from the combining form -(o)eidḗs as in anthrōpoeidḗs (human-like), and is cognate with French -oïde as in anthropoïde and Spanish -oide(o) as in both antropoide (adjective) and antropoideo (noun).

Some suffixes fall into more or less parallel sets according to use and background; for example, three suffixes for causative and inceptive verbs: vernacular -en (harden to make or become hard), Latinate -ify (purify to make or become pure), and GREEK -ize (systematize to make or become systematic). The conditions for using such suffixes are strictly circumscribed: no *hardize, *puren, *systemify (although the third is conceivable, on the model of humidify). Great variation is possible in a single form or group of related forms, as with the Latin form whose masculine is -arius, feminine -aria, neuter -arium. This has entered English in at least four ways: original forms unchanged, as ? in denarius, urticaria, aquarium; as the genderless -ary in aviary, honorary, primary, salary; as French -aire (contrast legionnaire/legionary, commissionaire/commissioner); in the complex forms -arian in disciplinarian, -arious in hilarious. In Latin, -arius was close to -aris (as in similaris, English similar); many words, especially from French, that contain the element -ar- derive from either -arius or -aris. In addition, a part of a word may look as though it contains a member of the -ar- group but does not, as with barbarian, whose division is barbar/ian, not *barb/arian.

Functions

The functions of a suffix are: to form a noun, adjective, or verb from another noun, adjective, or verb, in such patterns as noun from verb and verb from adjective; to provide a more or less clear-cut element of meaning in the complex word so formed: when -y is added to rock, an adjective is formed from a noun and the meaning of the phrase a rocky coastline can be paraphrased as ‘a coastline made up of rocks/covered with rocks/with a rock-like aspect’. Some suffixes function in isolation (for example, -ard in such words as communard, drunkard); no other element attaches to these words except the plural -s (but note bastardy). Others belong in sets, both associatively (-ist, -ism, -ize) and cumulatively (-ist, -istic, -istical, -istically). Such a cumulative set forms a derivational paradigm, a pattern whose potential can be exploited as needed. There are some 14 patterns of cumulative suffixation in English. Of these, four are vernacular and ten Neo-Latin, sometimes blending Latin and Greek. The VERNACULAR paradigms belong to the language at large, while the Neo-Latin PARADIGMS tend to be limited to educational, technical, and scientific registers. Such paradigms indicate a higher level of regularity in English suffixation than is often supposed to exist, but for every more or less regular system there are many incomplete or idiosyncratic arrangements in all areas and levels in which suffixes are involved. For example:

1. Vernacular.

The nouns sand, milk provide the usually literal sandy and milky, but the nouns brain, hand provide brainy and handy, which are figurative and do not refer directly to brain or hand.

2. Latinate.

The noun nation is the base of the adjective national. The noun nationality is formed from it, but not usually the noun nationalness. Compare the noun use, the etymological base of the adjective usual, which has little to do with using things. From it, usualness is formed, but not *usuality.

3. Greek.

The adjective syllogistic derives from the noun syllogism, not from *syllogy, but eulogistic currently derives from the noun eulogy, not eulogism. Where biology begets biological and not *biologistic, eulogy begets eulogistic and not in present-day English *eulogical.

Gradations of meaning and use

Suffixes display all kinds of relationships between form, meaning, and function. Some are rare and have only vague meanings, as with the -een in velveteen. Some have just enough uses to suggest a meaning, as with -iff in bailiff, plaintiff, suggesting someone involved with the law, and -ain in captain, suzerain, suggesting someone with power. Some may be rare and apparently inert, yet come to life when needed: the Greek suffix -ad marks a nymph (dryad, oread), a number group (monad, triad), an epic (Iliad, Dunciad), and an activity occurring on an epic scale (Olympiad). Few nymphs and number groups are now created, but the recent Asiad as the name for pan-Asian games indicates that -ad is still available for epic events, at least in the context of athletics.

THEMATIC GROUPS OF SUFFIXES

The major semantic groups of suffixes and suffix-like elements are listed, with examples of their use, in the groups below. The same element or a variant of an element may appear in more than one group, because many elements have more than one meaning and use. No attempt is made to signal the degree of productivity of any suffix listed.

SUFFIXES AND STRESS

Many suffixes of Latin and Greek origin trigger a shift in STRESS (technically, stress shift or accent shift) when added to polysyllabic bases: for example, -ity attracts stress to the syllable preceding it (cómplex/compléxity). No vernacular suffixes cause stress shift, nor do all classical suffixes do so: for example, there is no shift in the vernacular set shárp/shárpen/shárpener, nor in the Romance set devélop/devélopment, but a shift occurs when this set is extended with -al: devélopment/developméntal. In terms of stress shift, there are three groups of suffixes:

1. Vernacular: no shift

Suffixes and compounding elements which do not cause stress shift: -dom kingdom, -ed salted, red-haired, -en darken, -er writer, -erly easterly, -ern northern, -erner westerner, -ernmost southernmost, -ful hopeful, fulness truthfulness, -hood adulthood, -iness dirtiness, -ing startling, soap-making, -ish roundish, -ishness reddishness, -less useless, -lessness meaninglessness, -let leaflet, -like stone-like, -liness loneliness, -ling hireling, -ly womanly, -ness darkness, -ship readership, -y sandy.

2. Romance and classical: no shift

Suffixes and compounding elements which do not cause stress shift: -able breakable, -age marriage, -al renewal, -ant dependant, -ar similar, -ary legionary, -cy accuracy, normalcy, -ible incorrigible, -ion attention, -ism Darwinism, -ist socialist, -ite meteorite, -ive suggestive, -ment development, -or dictator, -ure fixture. Although they do not themselves affect stress, they may occur in composites which do, such as -ability, in which the -ity attracts the stress to the syllable preceding it: téachable/teachabílity.

3. Classical: causing shift

The lists indicate the form which the shift takes when the words containing the suffixes are pronounced in isolation. Minor changes relating to primary or secondary stress may occur in the flow of longer utterances. When the suffix is attached, stress falls: (a) on the only syllable of the suffix: -ee referée, refugée, -eer auctionéer, enginéer, -ese Japanése, Vietnamése, -esque picturésque, Junoésque, -ette cigarétte, usherétte. (b) on the first syllable of a composite suffix with two syllables: -ation commendátion, degradátion, transformátion, -ition composítion, definítion, edítion, -ution dissolútion, revolútion, -atic dogmátic, systemátic, -etic energétic pathétic, -iety sobríety, socíety -mental developméntal, experiméntal, -ental continéntal, -ential presidéntial, (c) one syllable before the (composite) suffix: -an subúrban, -ian Canádian, -ial torréntial, -eal larýngeal, -ual resídual, -ify humídify, -ic económic, históric, -ical económical, histórical, -ity compléxity, informálity, (d) two syllables before the suffix: -al colónial, indústrial, -ar molécular, rectángular, -ize decéntralize, réalize, -ous censórious, labórious.
