How productive a w-f process is depends on how many new lexemes can be formed by it.
Affixation is a productive word-formation process in which new lexemes are produced by adding affixes to at least one root lexeme. (prefixaton, suffixation)
-tion, -ity, -er, -ness, -ism, -ment, -ant, -ship, -age, -ery
-ate, -en, -ify, -ise/-ize
-ly, -ily, -ally, -wise, -wards
un-, im-, in-, il-, ir-, dis-, non-, mis-, de-
-y/-ie, -ock, - ette, -let, -ling, -o
Compounding is a process of creating new words by combining at least two root morphemes (household, highlight).
1.Simple (sunlight= sun+light)
2. Complex (backbencher= back+bench+er)
The meaning of the morphemes is compositional (can be interpreted literally).
ex.= classroom, sunlight, deaf-mute
They cannot be interpreted literally.
ex.= chatterbox, pickpocket, nightcap, pick-up (n)
compound adjective- deaf-mute, blue-eyed
compound verb- double-click, outrun
compound adverb- thereafter, sometimes
Conversion a very productive w-f process in which a word is converted into a different word-class without adding any affix. (same spelling, same pronunciation)
(bottle- to bottle)
A type of conversion where a noun is not converted to a verb, but it is pre-modified by verbs such as have, get, take, make, give (ex. take a shower, have a smoke)
Clipping
Acronymy
Initialisms
Graphical Abbreviation
… a w-f process that involves cutting off one or more letters or syllables of a word.
Initial- aeroplane-> plane; robot-> bot
Final- photograph-> photo; gymnasium-> gym
Transparent- the clipped lexeme directly corresponds to a part of the original word. (sister->sis)
Non-transparent- the clipped lexeme does not directly correspond to a part of the original word. (umbrella-> brolly)
Acronyms are abbreviations formed from the initial letters of multiword expressions and read as regular words. (NATO)
Initialisms- -//- but they are always spelled out (BBL- bi: bi: el)
