Part-of-speech tagging is harder than just having a list of words and their parts of speech, because some words can represent more than one part of speech at different times, and because some parts of speech are complex. This is not rare—in natural languages (as opposed to many artificial languages), a large percentage of word-forms are ...
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 to a root morpheme (word) are ...
Phonemic awareness is a part of phonological awareness in which listeners are able to hear, identify and manipulate phonemes, the smallest mental units of sound that help to differentiate units of meaning . Separating the spoken word "cat" into three distinct phonemes, /k/, /æ/, and /t/, requires phonemic
The word there in such sentences has sometimes been analyzed as an adverb, or as a dummy predicate, rather than as a pronoun. [17] However, its identification as a pronoun is most consistent with its behavior in inverted sentences and question tags as described above.
Both WSD and part-of-speech tagging involve disambiguating or tagging with words. However, algorithms used for one do not tend to work well for the other, mainly because the part of speech of a word is primarily determined by the immediately adjacent one to three words, whereas the sense of a word may be determined by words further away.
The ancient work on the grammar of the Tamil language, Tolkāppiyam, argued to have been written around 2nd century CE, [8] classifies Tamil words as peyar (பெயர்; noun), vinai (வினை; verb), idai (part of speech which modifies the relationships between verbs and nouns), and uri (word that further qualifies a noun or verb).

For most spoken languages, the boundaries between lexical units are difficult to identify; phonotactics are one answer to this issue. One might expect that the inter-word spaces used by many written languages like English or Spanish would correspond to pauses in their spoken version, but that is true only in very slow speech, when the speaker deliberately inserts those pauses.
