A suffix is an ending we can attach to a word to express grammatical relationships (inflectional suffix) or to create a new word (derivational suffix).
Inflectional suffixes
Inflectional suffixes can be used to mark:
- a plural noun e.g. house → houses (-s, -es or -ies suffix)
- a past tense verb e.g. walk → walked (-ed suffix)
- a possessive noun e.g. dog → dog’s (-‘s or -s’ suffix)
- a 3rd person singular present tense verb e.g. jump → jumps (-s suffix)
- a present (-ing) participle e.g. fly → flying (-ing suffix)
These endings carry grammatical information. They usually change the form of a word rather than its class – although the -ly suffix is added to an adjective to create an adverb e.g. slow → slowly.
Derivational suffixes
We use derivational suffixes to create new words which often have a different word class to the original word or base.
- kind (Adj) + -ness → kindness (N) [-ness is a Latin suffix denoting ‘quality of’]
- defence (N) + -less → defenceless (Adj) [-less is a Latin suffix denoting ‘without’)
- able (Adj) + -ity → ability (N) [-ity is a Latin suffix denoting ‘state’, ‘condition’]
- dedicate (V) + ion → dedication (N) [-tion is a Latin suffix denoting ‘act of’]
- pac (N, peace; from the Latin pax) + ify → pacify (V) [-ify is a Latin suffix denoting ‘to make’]
-ism and -ist
But enough about the general cases, the source of this post was a radio discussion about the lack of older women on television news. The presenter used the word lookist to describe our society and it seemed a great place to start …
The OED cites its use as an adjective in the phrase ‘an unrepentant lookist pig’ (i.e. relating to discrimination on the
grounds of appearance’), and as the noun
lookism (i.e. prejudice or discrimination on the basis of appearance)
as early as 1978. In 1990, the noun lookist (i.e. a person who discriminates on the grounds of appearance) is recorded.
This word formation follows a well-worn pattern using the Greek suffixes -ism (i.e. ‘belief in’) and -ist (i.e. ‘one who believes in’).
-ism
Many of our traditional -ism nouns use a Greek base, often loans which have entered English through Latin and French borrowings.
aestheticism: belief in or pursuit of what is beautiful or attractive to the senses, rather than appealing to the ethical or rational (first use 1840)
From the ancient Greek αισθητικòς (= aesthetic i.e. ‘of or relating to the senses’) + -ism (i.e. ‘belief in’)
amateurism: belief in or pursuit of the amateur (first use 1868)
From the French amateur and the Latin amator (‘lover’), amare (‘to love’) – from the 18th century, a person who does anything as a pastime rather than as a profession (now often disparaging)
cannibalism: the practice of eating flesh of one’s own species (first use 1796)
From the 16th century Spanish Canibales, originally one of the names for the Carib tribe of the West Indies, who are recorded as being ‘anthropohagi’ (Latin plural of anthropophagus, from the Greek ανθρωποφαγος, ‘man-eating’)
The -ism suffix can be used to denote a range of meanings:

A historical perspective
Following the Latin and Greek models, this helpful little suffix has been used to form the names of religious and philosophical systems, and to describe distinctive ways of looking at the world. We can trace its use over centuries:
paganism 
Christianism (1576, now obsolete)martialism (1608)Stoicism (1626)latitudinarianism (1676)
Islamism (1696)Predestinarianism (1722)
Buddhism (1801)Luddism (1812)imperialism (1858)reincarnationism (1907)
Rachmanism (1963)Orwellianism (1976)bioterrorism (1987)
cyberterrorism (1994)prepperism (i.e. the belief that we need to make advance preparations in order to be able to cope with any disaster, or the end of the society as we know it – not yet in dictionaries, but being used on the internet 2012)
-ism words chart changes in our scientific and technological capabilities, in our attitudes, and in our broadening experiences of other cultures and belief systems.
Evidence that the -ism suffix continues to be linguistically central to our ever-growing word stock can be seen in words like obeseism and gingerism. These are recorded in Wiktionary, are used in the media and can be found in all kinds of contexts online, but have not yet made it into an up-dated entry in the OED. The suffix even became a noun in its own right as early as 1680: ism, any distinctive doctrine, theory or practice (often used disparagingly).
-ist
Our -ist nouns correspond to the French -iste, Latin –ista, Greek ιστης. Initially, these were endings attached to –ize/ -ise verb stems to form an agent noun (e.g.antagonize → antagonist; ), but in English the suffix is now used more widely. It can be used with -ism nouns (e.g. pacifism → pacifist), with adjectives (e.g.fatal → fatalist), and by analogy (psychiatry → psychiatrist). These -ist nouns can name the followers of a particular group or principle, or the practitioners of a particular process, art or skill. As a noun in its own right, ist was first used in 1811.
baptist: a person who baptizes (first use 1200); member of the religious body that practises baptism by total immersion for believers (first use 1654)
From the Old French baptiste, the Latin baptista (‘lover’) and the Greek βαπτιστης
chemist: a person who practices or studies chemistry (first use 1559)
From Middle French chimiste and Latinchimista + -ist
Marxist: a person who believes in the theories and principles of Karl Marx (first use 1873)
From the name of the revolutionary thinker and philosopher Karl Marx (1818-1883)
The -ist suffix can be used to denote the following meanings:
1. ‘one who believes in …’
Methodist (first use 1593; from Latin methodus, ‘mode of proceeding’, and Greek μεθοδος, ‘pursuit of knowledge’)
royalist (first use 1605; from Anglo-Norman roial and Middle French royaliste)
