Origin and productivity
Native affixes are those that existed in the OE period or were formed from OE words, such as un-, mis-, be-, out-, over-, -ness, -dom, -hood, -ly, –er. Foreign affixes came as a part of loan words from Latin, Greek, French, or other languages. Examples: ab-(L), bi-(L), dis-(L), re-(L), kilo(Gk), poly-(Gk), mal-(F), -ic(Gk), -ism(Gk), ist(Gk), -able (F), -ize(F).

Morpheme: definition
Morpheme is the smallest meaningful linguistic unit of language, not divisible or analyzable into smaller forms. Words are composed of morphemes. What is usually considered a single word in English may be composed of one or more morphemes.

Allomorph
An allomorph is any of the variant forms of a morpheme as conditioned by position or adjoining sounds. e.g. the morpheme of plurality {-s}: /s/ after the sounds /t, p, k/ /z/ after /d, b, g, l/; /iz/ after /s, z, …/

Morphe and productivity
Affixes (such as re-, un-, -able, -ize) are called productive or living when they can be used to form new words. Those that are no longer used to form new words are termed dead or unproductive. e.g. for- as in forget, forgive, forbid; with- as in withdraw, withhold, withstand, -ant or -ent as in servant, different.
Allomorph
A prefix like im- occurs before p, b, or m (imperfect, imbalance, immobile). Its allomorphs are ir- before r (irregular, irresponsible); il- before l (illogical, illegal); in- before all other consonants and vowels (inflexible, incomplete).
Affix: derivational affix
Derivational affixes are added to other morphemes to create new words. They can be further divided into prefixes and suffixes.
Root
Alternatively, morphemes may be divided into roots (or root morphemes) and affixes (or affixational morphemes).
Root
Roots is the basic unchangeable part of a word, and it conveys the main lexical meaning of the word. e.g. work, workable, worker, worked, working
Affix: prefix and suffix
Derivational morphemes or derivational affixes are commonly subdivided into prefixes and suffixes. Affixes before the word are called prefixes; those after are called suffixes.

Affix: inflectional affix
Affixes attached to the end of words to indicate grammatical relationships are inflectional, thus known as inflectional morphemes. e.g. cats, walked, walking, John’s book…

book books bookish bookcase tolerate tolerance tolerant toleration tolerable intolerable telephone telegram telescope telecommunication -s, -ate, -ish, -case, in-, -able
Affix
Affixes are forms that are attached to words or word elements to modify meaning or function. According to the functions of affixes, we can put them into two groups: inflectional and derivational affixes.
