For a large class of cases—though not for all—in which we employ the word ‘meaning’ it can be defined thus: the meaning of a word is its use in the language.
— Wittgenstein (PI I.43)
What a word means also depends on where and when you use it. ‘Queen Anne’s Lace’ is one of several popular names for the common weed Daucus Carota – in North America. In England, ‘Queen Anne’s Lace’ is the name of an entirely different plant, Anthriscus sylvestris (Heiser 2003, 44).
