Interjections in American Sign Language
Interjection is a word or a short exclamation that conveys emotion. It has no real grammatical value nor connection to any other part of the sentence.
The word "interjection" literally means "thrown in between" from the Latin terms "inter" ("between") and "iacere" ("throw").
The following familiar interjections in vocal English are: ah, eh, er, um, hey, oh, ouch, uh, huh, well. They are usually expressed in a spoken form rather than in writing.
Some of the examples of ASL interjections are as follows: "OH", "PSHAW", "HEY", and many other non-manual expressions. Social immersion is necessary to fully understand how to use them correctly in subtle contexts.
