This document discusses word formation processes, specifically focusing on prefixation. It defines key terms like base, stem, and affix. It then describes the different types of prefixes, including: 1. Reversative/privative prefixes that reverse or deprive the base, like un-, de-, and dis-. 2. Pejorative prefixes that convey a negative meaning, like mis-, mal-, and pseudo-. 3. Degree/size prefixes that indicate levels, like arch-, super-, over-, and mini-. 4. Attitude prefixes that show position or opposition, like co-, counter-, anti-, pro-. 5. Locative and time/order prefixes about place and sequence,

1. Word-formation
BASE ( as distinct from STEM- a part of the word remaining after every
affix has been removed)
e.g. friend – stem
friendly= friend+ly ( stem = base + affix)
unfriendly = un + friendly (friendly is a base but not the stem)
Derivation:
friend noun
friend+ly noun >adjective
un+friend+ly adjective > adjective
un+friend+li-ness adjective > noun

2. Chief processes by which the BASE may be modified:
AFFIXATION
a) Prefixation -adding a prefix to the base, with or without a change of
word-class e.g. author – co-author
b) Suffixation- adding a suffix to the base, with or without a change of
word-class e.g. drive – driver
CONVERSION (‘zero affixation’) assigning the base to a different word
class without changing its form ( e.g. drive v.- drive n.)
COMPOUNDING – adding one base to another ( hang+man=hangman)
