Morpheme
In linguistics,
a morpheme is the smallest semantically meaningful unit in a language. The field of
study dedicated to morphemes is called morphology. A morpheme is not identical to
a word, and the
principal difference between the two is that a morpheme may
or may
not stand alone, whereas a word, by definition, is a freestanding unit of
meaning. Every word comprises one or more morphemes.
Example :
- "Unbreakable" comprises three morphemes: un- (a bound morpheme signifying "not"), -break- (the root, a free morpheme), and -able (a bound morpheme signifying "doable").
- Allomorphs of the plural morpheme for regular nouns: /s/ (e.g. in cats /kæts/), /ɨz/ (e.g. in dishes /dɪʃɨz/), and /z/ (e.g. in dogs /dɒɡz/).
Classification of morphemes
Free vs. bound
Every morpheme can be classified as either free or bound. These categories are mutually exclusive, and as such, a given morpheme will belong to exactly one of them.- Free morphemes can function independently as words (e.g. town, dog) and can appear with other lexemes (e.g. town hall, doghouse).
- Bound morphemes appear only as parts of words, always in conjunction with a root and sometimes with other bound morphemes. For example, un- appears only accompanied by other morphemes to form a word. Most bound morphemes in English are affixes, particularly prefixes and suffixes. Bound morphemes that are not affixes are called cranberry morphemes, their nomenclature derived from the bound, non-affix function of cran- in the word cranberry.
Derivational vs. inflectional
Bound morphemes can be further classified as derivational or inflectional.- Derivational morphemes, when combined with a root, change either the semantic meaning or part of speech of the affected word. For example, in the word happiness, the addition of the bound morpheme -ness to the root happy changes the word from an adjective (happy) to a noun (happiness). In the word unkind, un- functions as a derivational morpheme, for it inverts the meaning of the word formed by the root kind.
- Inflectional morphemes modify a verb's tense or a noun's number without affecting the word's meaning or class. Examples of applying inflectional morphemes to words are adding -s to the root dog to form dogs and adding -ed to wait to form waited.

Attaching Affixes to Base Words and Word Stems
What are Prefixes and Suffixes?
Prefixes and suffixes are grammatical and lingual "affixes." Prefixes are affixed before and suffixes after a base word or word stem to add information. For example, with the word "prehistoric," the prefix is "pre-" meaning "before," the base word is "history" meaning "recorded events and knowledge", and the suffix is "-ic" meaning "relating to the science of."In other words, "prefix" simply refers to an attachment before or in front of, in this case, a shorter word or stem. In lingual terms, a "stem" is the main part of a word to which prefixes and suffixes can be added and may not necessarily be a word itself, such as "dod" in "doddle."
Similarly, "suffix" refers to an attachment after the end of an existing word or stem, serving to form a new word or functioning as an inflectional ending, for example, “s” or “es” to make for plurality.
Is an Affix a Single Syllable?
No, a prefix or suffix can be one or more syllables, depending on the root word from Latin or Greek or from any one of a host of other English lingual influences.Inflectional Suffixes
Are Endings such as "-ed," "-ing," and "-s" Suffixes?
Yes, endings that are create different forms of the same word are called "inflectional suffixes." There are very few inflectional suffixes but they occur rather frequently. They are:
-s, -es, -ies

Derivation (linguistics)
In linguistics, derivation is the process of forming
a new word on the basis of an existing word, e.g. happi-ness and un-happy
from happy, or determination from determine. Derivation
stands in contrast to the process of inflection,
which uses another kind of affix in order to form grammatical variants of the
same word, as with determine/determine-s/determin-ing/determin-ed.[1]
Generally speaking, inflection applies to all members of a part of
speech (e.g., every English verb has a past-tense form), while derivation
applies only to some members of a part of speech (e.g., the nominalizing suffix
-ity can be used with the adjectives modern and dense, but
not with open or strong).
A derivational suffix usually
applies to words of
one syntactic category and changes them into words
of another syntactic
category. For example, the English
derivational suffix
-ly changes adjectives into adverbs (slow
→ slowly).
Examples of English derivational patterns and their
suffixes:
- adjective-to-noun: -ness (slow → slowness)
- adjective-to-verb: -ise (modern → modernise) in British English or -ize (archaic → archaicize) in American English and Oxford spelling
- adjective-to-adjective: -ish (red → reddish)
- adjective-to-adverb: -ly (personal → personally)
- noun-to-adjective: -al (recreation → recreational)
- noun-to-verb: -fy (glory → glorify)
- verb-to-adjective: -able (drink → drinkable)
- verb-to-noun (abstract): -ance (deliver → deliverance)
- verb-to-noun (concrete): -er (write → writer)
Although derivational affixes do not necessarily alter
the syntactic category, they do change the meaning
of the base. In many cases, derivational affixes change both the syntactic
category and the meaning: modern → modernize ("to make
modern"). The change of meaning is sometimes predictable: Adjective +
ness → the state of being (Adjective); (white→ whiteness).
A prefix (write → re-write; lord
→ over-lord) will rarely change syntactic category in English. The
inflectional prefix un- applies to adjectives (healthy
→ unhealthy)and some verbs (do → undo), but rarely to
nouns. A few exceptions are the derivational prefixes en- and be-. En- (em-
before labials) is usually used as a transitive marker on
verbs, but can also be applied to adjectives and nouns to form transitive
verbs: circle (verb) → encircle (verb); but rich (adj) → enrich
(verb), large (adj) → enlarge (verb), rapture (noun) → enrapture
(verb), slave (noun) → enslave (verb).
Note that derivational affixes are bound
morphemes. In that respect, derivation differs from compounding by which free morphemes
are combined (lawsuit, Latin professor). It also differs from inflection
in that inflection does not create new lexemes but new word forms
(table → tables; open → opened).
Derivation can occur without any change of form, for
example telephone (noun) and to telephone. This is known as conversion or zero derivation.
Suffixes
A suffix is a group of letters placed at the end of a word to make a new word. A suffix can make a new word in one of two ways:- inflectional (grammatical): for example, changing singular to plural (dog > dogs), or changing present tense to past tense (walk > walked). In this case, the basic meaning of the word does not change.
- derivational (the new word has a new meaning, "derived" from the original word): for example, teach > teacher or care > careful
Inflectional suffixes
Inflectional suffixes do not change the meaning of the original word. So in "Every day I walk to school" and "Yesterday I walked to school", the words walk and walked have the same basic meaning. In "I have one car" and "I have two cars", the basic meaning of the words car and cars is exactly the same. In these cases, the suffix is added simply for grammatical "correctness". Look at these examples:

Derivational suffixes
With derivational suffixes, the new word has a new meaning, and is usually a different part of speech. But the new meaning is related to the old meaning - it is "derived" from the old meaning.We can add more than one suffix, as in this example:
derive (verb) + tion = derivation (noun) + al
= derivational (adjective)
There are
several hundred derivational suffixes. Here are some of the more common ones:

English
prefixes
English prefixes are affixes (i.e., bound morphemes that
provide lexical meaning) that are added before either simple roots or complex bases (or operands)
consisting of (a) a root and other affixes, (b) multiple roots, or (c) multiple
roots and other affixes. Examples of these follow:
- undo (consisting of prefix un- and root do)
- untouchable (consisting of prefix un-, root touch, and suffix -able)
- non-childproof (consisting of prefix non-, root child, and root proof)
- non-childproofable (consisting of prefix non-, root child, root proof, and suffix -able)
English words may consist of multiple prefixes: anti-pseudo-classicism
(containing both an anti- prefix and a pseudo- prefix).
In English, all prefixes are derivational. This contrasts with English
suffixes, which may be either derivational or inflectional.
