property. In non-technical language, it is the expression of one or more grammatical properties by sound. There are several kinds of exponents:
*Identity
*Affixation
*Reduplication
*Internal modification
*Subtraction
Identity
The identity exponent is both simple and common: it has no phonological manifestation at all.
An example in English:
DEER +
PLURAL → deer
Affixation
Affixation is the addition of an
affix
In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English ''-ness'' and ''pre-'', or inflectional, like English plural ''-s'' and past tense ''-ed''. They ...
(such as a
prefix
A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix ''un-'' is added to the word ''happy'', it creates the word ''unhappy''. Particu ...

infix
An infix is an affix inserted inside a word stem (an existing word or the core of a family of words). It contrasts with '' adfix,'' a rare term for an affix attached to the outside of a stem, such as a prefix or suffix.

Example in English:

PAST → ''wanted''
Reduplication
Reduplication is the repetition of part of a word.

:
दा ''dā'' ("give") +
PRESENT +
ACTIVE +
INDICATIVE +
FIRST PERSON +
SINGULAR → ददामि '' dadāmi'' (the ''da'' at the beginning is from reduplication of ''dā'' that involves a vowel change, a characteristic of
class 3 verbs in Sanskrit)
Internal modification
There are several types of internal modification. An internal modification may be
segmental, meaning it changes a sound in the root.
An example in English:
STINK +
PAST = stank (i becomes a)
An internal modification might be a
suprasegmental modification. An example would be a change in
pitch or
stress.
An example of the latter in English (acute accent indicates stress):
RECÓRD +
NOUN = récord
Subtraction
Subtraction is the removal of a sound or a group of sounds.
An example in French:
OEUF /œf/ ("egg") +
PLURAL = œufs /ø/ (final f is lost)
