Speech act - Wikipedia, the free encyclopedia
For example, are you using Searle's or Austin's definition of "illocution"? So, it depend on what you're being taught. If this is an assignment, you'd probably need to justify your classification.
Mary: "You owe me an apology"
My understanding is that all speech acts are locutionary. You can then decide if there is any illocutionary or perlocutionary force to the speech act. That is, it's not a decision of labelling a sentence as "locutionary" or "illocutionary".
In accordance with the categorisation on the Wikipedia page, the above Mary sentence has the illocutionary force of a directive - "speech acts that are to cause the hearer to take a particular action, e.g. requests, commands and advice". She is requesting an apology. If John did apologise, then Mary's sentence had the perlocutionary effect of gaining John's apology.
PS: This looks like homework, and you need to make all these judgements yourself.
