Editing Interjection (section)

=== Interjections and other word classes ===
Interjections are sometimes classified as [[Grammatical particle|particles]], a catch-all category that includes adverbs and [[onomatopoeia]]. The main thing these word types share is that they can occur on their own and do not easily undergo [[inflection]], but they are otherwise divergent in several ways. A key difference between interjections and onomatopoeia is that interjections are typically ''responses to'' events, while onomatopoeia can be seen as ''imitations of'' events.<ref name=":1">{{Cite journal|doi=10.1016/j.pragma.2014.11.011|title=Distinguishing onomatopoeias from interjections|last=Meinard|first=Maruszka E.

Interjections can also be confused with adverbs when they appear following a form of the verb “go” (as in "he went 'ouch!'"), which may seem to describe a manner of going (compare: 'he went rapidly'). However, this is only a superficial similarity, as the verb go in the first example does not describe the action of going somewhere. One way to differentiate between an interjection and adverb in this position is to find the speaker of the item in question. If it is understood that the subject of the utterance also utters the item (as in "ouch!" in the first example), then it cannot be an adverb.<ref name=":1" />

[[Routine speech|Routines]] are considered as a form of speech acts that rely on an understood social communicative pattern between the addressee and addressed. This differs from an interjection that is more of a strategic utterance within a speech act that brings attention to the utterance but may or may not also have an intended addressed (directed at an individual or group).<ref name=":1" /> In addition, routines generally are multi-word expressions whereas interjections tend to be single utterances.<ref name=":0" />

Under a different use of the term 'particle', particles and interjections can be distinctions in that particles cannot be independent utterances and are fully a part of the syntax of the utterance. Interjections, on the other hand, can stand alone and also are always preceded by a pause, separating them from the grammar and syntax of other surrounding utterances.<ref name=":0" />
