In morpheme-based morphology, a morpheme is the smallest linguistic unit that has semantic meaning. Morpheme-based morphology is a view on morphology with the following three basic axioms Baudoin’s SINGLE MORPHEME HYPOTHESIS Roots and affixes have the same Semantics is the study of meaning in communication The word derives from Greek σημαντικός ( semantikos) "significant" from This article is about meaning as it is studied in the discipline of linguistics In spoken language, morphemes are composed of phonemes (the smallest linguistically distinctive units of sound), and in written language morphemes are composed of graphemes (the smallest units of written language). The phoneME project is Sun Microsystems reference implementation of Java virtual machine and associated libraries of Java ME with source licensed under the GNU In Typography, a grapheme is the fundamental unit in written language.

The concept morpheme differs from the concept word, as many morphemes cannot stand as words on their own. A word is a unit of Language that carries meaning and consists of one or more Morphemes which are linked more or less tightly together and has a Phonetic A morpheme is free if it can stand alone, or bound if it is used exclusively alongside a free morpheme. Its actual phonetic representation is the morph, with the morphs representing the same morpheme being grouped as its allomorphs.

English example:

The word "unbreakable" has three morphemes: "un-" (meaning not x), a bound morpheme; "-break-", a free morpheme; and "-able", a bound morpheme. "un-" is also a prefix, "-able" is a suffix. An affix is a Morpheme that is attached to a stem to form a word In Grammar, a suffix (also postfix, ending) is an Affix which is placed at the end of a word Both are affixes. An affix is a Morpheme that is attached to a stem to form a word

The morpheme plural-s has the morph "-s", IPA: [s], in cats ([kæts]), but "-es", [ɪz], in dishes ([dɪʃɪz]), and even the voiced "-s", [z], in dogs ([dɒgz]). These are the allomorphs of "-s". It might even change entirely into -ren in children.

Types of morphemes

• Free morphemes like town, and dog can appear with other lexemes (as in town hall or dog house) or they can stand alone, i. In Linguistics, free morphemes (sometimes also referred to as unbound morphemes) are Morphemes that can stand alone unlike Bound morphemes which For its use in the context of Computer Science see Lexical analysis. e. "free".
• Bound morphemes (or affixes) like "un-" appear only together with other morphemes to form a lexeme. In Etymology, a bound morpheme is a Root morpheme that cannot stand alone as an independent word An affix is a Morpheme that is attached to a stem to form a word Bound morphemes in general tend to be prefixes and suffixes. Unproductive, non-affix morphemes that exist only in bound form are known as "cranberry" morphemes, from the "cran" in that very word. In linguistic morphology, a cranberry morpheme (or fossilized term) is a type of Bound morpheme that cannot be assigned a meaning or a grammatical function
• Derivational morphemes can be added to a word to create (derive) another word: the addition of "-ness" to "happy," for example, to give "happiness. In Linguistics, derivation is "Used to form new words as with happi-ness and un-happy from happy, or determination from " They carry semantic information. Semantics is the study of meaning in communication The word derives from Greek σημαντικός ( semantikos) "significant" from
• Inflectional morphemes modify a word's tense, number, aspect, and so on (as in the "dog" morpheme if written with the plural marker morpheme "-s" becomes "dogs"). In Grammar, inflection or inflexion is the way language handles grammatical relations and relational categories such as tense, mood, voice They carry grammatical information.
• Allomorphs are variants of a morpheme, e. This article is about a linguistic term See Pseudomorph for another g. the plural marker in English is sometimes realized as [-z], [-s] or [-ɪz].

Other variants

• Null morpheme
• Root morpheme
• Word stem

Morphological analysis

In natural language processing for Japanese, Chinese and other languages, morphological analysis is the process of segmenting a given sentence into a row of morphemes. In morpheme-based morphology, a null morpheme is a Morpheme that is realized by a phonologically null Affix (an empty string of phonological The root is the primary lexical unit of a Word, which carries the most significant aspects of semantic content and cannot be reduced into smaller constituents In Linguistics, a stem (sometimes also theme) is the part of a word that is common to all its inflected variants Natural language processing ( NLP) is a subfield of Artificial intelligence and Computational linguistics. is a language spoken by over 130 million people in Japan and in Japanese emigrant communities It 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. Part-of-speech tagging ( POS tagging or POST) also called grammatical tagging or word-category disambiguation, is the process of marking up the Famous Japanese morphological analysers include Juman, ChaSen and Mecab. Chasen is a Christian rock band from Greenville South Carolina.
