For example, in English the root catch and the suffix -ing are both morphemes; catch may appear as its own word, or it may be combined with -ing to form the new word catching. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect.
These sample English words have the following morphological analyses: "Unbreakable" is composed of three morphemes: un-(a bound morpheme signifying negation), break (a verb that is the root of unbreakable: a free morpheme), and -able (a bound morpheme as an adjective suffix signifying "capable of, fit for, or worthy of").

Morphological parsing, in natural language processing, is the process of determining the morphemes from which a given word is constructed. It must be able to distinguish between orthographic rules and morphological rules. For example, the word 'foxes' can be decomposed into 'fox' (the stem), and 'es' (a suffix indicating plurality).
In the example the left hand side is the surface form (input), and the right hand side is the lexical form (output). This order is used in morphological analysis where a lexical form is generated from a surface form. In morphological generation this order would be reversed.
Morphological analysis may refer to: Morphological analysis (problem-solving) or general morphological analysis, a method for exploring all possible solutions to a multi-dimensional, non-quantified problem; Analysis of morphology (linguistics), the internal structure of words Morphological parsing, conducted by computers to extract ...
Morphophonology (also morphophonemics or morphonology) is the branch of linguistics that studies the interaction between morphological and phonological or phonetic processes. . Its chief focus is the sound changes that take place in morphemes (minimal meaningful units) when they combine to form wo
Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, one effect of the English derivational suffix -ly is to change an adjective into an adverb (slow → slowly).
A lexeme (/ ˈ l ɛ k s iː m / ⓘ) is a unit of lexical meaning that underlies a set of words that are related through inflection.It is a basic abstract unit of meaning, [1] a unit of morphological analysis in linguistics that roughly corresponds to a set of forms taken by a single root word.
