The aim of the paper is to analyse and explicate the meanings the word „identification“ has in common language, philosophy of language and in P. Tichý’s theory of constructions. The author distinguishes acts of identification performed by a man from identification carried out by some expressions. He tries to argue that in case of expressions identifying is the same as referring and in case of Tichý’s constructions identifying means constructing (as it is defined in Tichý‘s theory of constructions).
