Is the branch of linguistics
that deals with words, their
internal structure, and how
they are formed.
Morpheme: Is the smallest linguistic piece
with a grammatical function. It may consist
of a word, such as "hand" or a meaningful
piece of a word, such as the "-ed" in looked.
Affixation: An affix is a bound
morpheme that occurs before
or after on within a base,
commonly known as prefixes,
suffixes and infixes.
Prefixes: bound morphemes that
occur before a base. In English,
are small class of morphemes.
Their meanings are often those
of English prepositions and
adverbials.
Compound word: is a lexeme containing two or
more potential stems that has not subsequently
been subjected to derivatonal process.
Conversion: Is the derivational process
whereby an item changes its word-class
without the addition of an affix:
Unpredicatable Formations: These kinds of
formation are also termed "oddities" by
Arnoff (1976) who points out that many of
these types depend on orthography to a
certain degree.
Clipping: It means cutting off the
beginning or the end of a word, or both,
leaving a part to stand for a whole: lab,
dorm, prof, exam.
Blending: is the fusion of two words into one,
ussually the first part of one word with the part of
another as in gasohol (gasoline and alcohol).
Acronyms: they are words
derived from the initials of
several words.:
RADAR - Radio detecting and ranging LASER - Light amplification by the stimulated
emission of radiation. NATO - The North Atlantic Treaty Organization. UNICEF - The United
Nations International Children's Emergency Fund. SCUBA - Self-contained underwater
breathing apparatus. WASP - White anglo saxon protestant. Read more at

new word from another adding an
affix:
Coinage: it is the invention of a
new word: aspirin, nylon
