A morpheme is the smallest meaningful lexical item in a language. A morpheme is not necessarily the same as a word. The main difference between a morpheme and a word is that a morpheme sometimes does not stand alone, but a word, by definition, always stands alone. The field of linguistic study dedicated to morphemes is called morphology.
In English, when a morpheme can stand alone, it is considered a root because it has a meaning of its own (such as the morpheme cat). When it depends on another morpheme to express an idea, it is an affix because it has a grammatical function (such as the –s in cats to indicate plurality).[1]. However this definition is not universal and it does not apply to, e.g. Latin where many roots cannot stand alone. For instance, the Latin root reg- (king) must always be suffixed with a case marker: rex (reg-s), reg-is, reg-i, etc. In a language like Latin, a root can be defined as the main lexical morpheme of a word.

Examples
  • "Unbreakable" is composed of three morphemes: un- (a bound morpheme signifying "not"), -break- (the root, a free morpheme), and -able (a free morpheme signifying "can be done").
  • Allomorphs of the plural morpheme for regular nouns: /s/ (e.g., in cats /
    kæts
    /), /ɪz, əz/ (e.g., in dishes /
    dɪʃɪz
    /), and /z/ (e.g., in dogs /
    dɒɡz
    /).
Classification of morphemes
Free and bound morphemes
Main article: Bound and unbound morphemes
Every morpheme can be classified as either free or bound.[2] Since the categories are mutually exclusive, a given morpheme will belong to exactly one of them.
Classification of bound morphemes
Bound morphemes can be further classified as derivational or inflectional morphemes. The main difference between derivational morphemes and inflectional morphemes is their function in relation to words.
Derivational Bound morphemes
Derivational morphemes
Derivational morphemes, when combined with a root, change the semantic meaning or the 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 since it inverts the meaning of the root morpheme (word) kind. Generally, morphemes that affix (i.e., affixes) to a root morpheme (word) are bound morphemes.
Inflectional bound morphemes
Inflectional morphemes
Inflectional morphemes modify the tense, aspect, mood, person, or number of a verb, or the number, gender, or case of a noun, adjective, or pronoun, without affecting the word's meaning or class (part of speech). Examples of applying inflectional morphemes to words are adding -s to the root dog to form dogs, or adding -ed to wait to form waited. An inflectional morpheme changes the form of a word. English has eight inflections.[3][4]
Allomorphs
Allomorphs are variants of a morpheme that differ in pronunciation but are semantically identical. For example, the English plural marker -(e)s of regular nouns can be pronounced /-s/ (bats), /-z/, (bugs), or /-ɪz, -əz/, (buses), depending on the final sound of the noun's plural form.

Zero-Morpheme
This section needs expansion with: at least a proper definition of the term. You can help by adding to it. (December 2019)
A zero-morpheme, is a type of morpheme that carries semantic meaning but is not represented by auditory phonemes. They are often represented by /Ø/ within glosses.[5]
Generally, these types of morphemes have no visible changes. For instance, sheep is both the singular and the plural form. The intended meaning is thus derived from the Co-occurrence determiner (in this case, "some-" or "a-").[6]
Content vs. function
Content morphemes express a concrete meaning or content, and function morphemes have more of a grammatical role. For example, the morphemes fast and sad can be considered content morphemes. On the other hand, the suffix -ed is a function morpheme since it has the grammatical function of indicating past tense.
Both categories may seem very clear and intuitive, but the idea behind them is occasionally harder to grasp since they overlap with each other.[7] Examples of ambiguous situations are the preposition over and the determiner your, which seem to have concrete meanings but are considered function morphemes since their role is to connect ideas grammatically.[8] Here is a general rule to determine the category of a morpheme:
Other features
Roots are composed of only one morpheme, while stems can be composed of more than one morpheme. Any additional affixes are considered morphemes. For example, in the word quirkiness, the root is quirk, but the stem is quirky, which has two morphemes.
Moreover, some pairs of affixes have the same phonological form but have a different meaning. For example, the suffix –er can be either derivative (e.g. sellseller) or inflectional (e.g. smallsmaller). Such morphemes are called homophonous.[8]
Some words might seem to be composed of multiple morphemes but are not. Therefore, not only form but also meaning must be considered when identifying morphemes. For example, the word relate might seem to be composed of two morphemes, re- (prefix) and the word late, but it is not.[citation needed] Those morphemes have no relationship with the definitions relevant to the word like "to feel sympathy," "to narrate," or "to be connected by blood or marriage."
Furthermore, the length of a word does not determine whether or not it has multiple morphemes. The word Madagascar is long and might seem to have morphemes like mad, gas, and car, but it does not. Conversely, some short words have multiple morphemes (e.g. dogs = dog + s).[8]
Morphological icons
Morphological icons are images, patterns or symbols that relate to a specific morpheme.[9] For children with dyslexia, it has been shown to be an effective way of building up a word. The word 'inviting' as an example is made up of two commonly used morphemes, 'in-' and '-ing'. A morphological icon for 'in-' could be an arrow going into a cup, and '-ing' could be an arrow going forward to symbolise that something is in action (as in being, running, fishing).
The concept of combining visual aid icons with morpheme teaching methods was pioneered from the mid 1980s by Neville Brown.[10] He founded the Maple Hayes school for dyslexia in 1981, where he later improved the method alongside his son, Daryl Brown. The school's curriculum uses morphological icons as a learning aid.[11]
Morphological analysis

In natural language processing for Japanese, Chinese, and other languages, morphological analysis is the process of segmenting a sentence into a row of morphemes. Morphological analysis is closely related to part-of-speech tagging, but word segmentation is required for these languages because word boundaries are not indicated by blank spaces.[citation needed]
The purpose of morphological analysis is to determine the minimal units of meaning in a language or morphemes by using comparisons of similar forms: for example, comparing forms such as "She is walking" and "They are walking," rather than comparing either with something completely different like "You are reading." Thus, the forms can be effectively broken down into parts and the different morphemes can be distinguished.
Similarly, both meaning and form are equally important for the identification of morphemes. For instance, an agent morpheme is an affix like -er that transforms a verb into a noun (e.g. teachteacher). On the other hand, –er can also be a comparative morpheme that changes an adjective into another degree of the same adjective (eg.. smallsmaller). Although the form is the same, the meanings are different. Also, the opposite can occur, with the meaning being the same but the form being different.[8]

In generative grammar, the definition of a morpheme depends heavily on whether syntactic trees have morphemes as leaves or features as leaves.
Given the definition of a morpheme as "the smallest meaningful unit," nanosyntax aims to account for idioms in which an entire syntactic tree often contributes "the smallest meaningful unit." An example idiom is "Don't let the cat out of the bag." Here, the idiom is composed of "let the cat out of the bag." This might be considered a semantic morpheme that is itself composed of many syntactic morphemes. Other cases of the "smallest meaningful unit" being longer than a word include some collocations such as "in view of" and "business intelligence", in which the words together have a specific meaning.
The definition of morphemes also plays a significant role in the interfaces of generative grammar in the following theoretical constructs:
