  Whereas an act of speech is any act of uttering[3] meaningful words, ‘speech act’ is a term of art. As a first approximation, speech acts are those acts that can (though need not) be performed by saying that one is doing so. On this conception, resigning, promising, asserting and asking are all speech acts, while convincing, insulting and growing six inches are not. One can, for instance, resign by saying, “I resign…”, although one can also resign from a position without describing oneself as doing so. However, this conception is too inclusive, since it also counts whispering as a speech act even though one can whisper a string of nonsense words without meaning anything. Instead a more accurate characterization of speech acts builds on Grice’s notion of speaker meaning. This notion is discussed further in Section 5 below, but for now it is enough to note that in looking at my watch, I might be trying to tell the time; or I might be trying to indicate to you that it’s time for us to leave. The latter (but not the former) is a case of speaker meaning.
