Editing Interjection (section)

== Meaning and use ==
In contrast to typical words and sentences, the function of most interjections is related to an expression of feeling, rather than representing some idea or concept.<ref name=":3">Goddard, C. (2014). Interjections and emotion (with special reference to “surprise” and “disgust”). ''Emotion Review'', ''6''(1), 53-63</ref> Generally, interjections can be classified into three types of meaning: volitive, emotive, or cognitive.<ref name=":3" />
* '''Volitive''' '''interjections''' function as imperative or directive expressions; requesting or demanding something from the addressee (e.g., ''Shh!'' = "Be quiet!";<ref name=":3" /> ''Boo!'' as in ''"Boo!" she cried, jumping to frighten him'')''.
* '''Emotive''' '''interjections''' are used to express emotions, such as disgust and fear (e.g., ''Yuck!'' expressing disgust;<ref name=":3" /> ''Boo!'' signalling contempt as in ''Boo! Shame on you'' or by audience members or spectators after a performance).
* '''Cognitive interjections''' express thoughts which are more related to cognition, or information known to the speaker of the utterance (e.g., ''Um!'' indicating confusion or thinking).<ref name=":3" /> 
While there exists some apparent overlap between emotive and cognitive interjections, as both express a feeling, cognitive interjections can be seen as more related to knowledge of something (i.e., information previously known to the speaker, or recently learned).<ref name=":3" />
