frozen - a frozen or stereotyped form is a (usually) phrase or short expression which has maintained its form while its literal meaning has weakened: 'one may discern various levels of linguistic activity. Originally, the Christian confessions of faith were essentially expressive acts; but the exclamations eventually crystallised into formulas which had the same locutionary force (since the facts referred to did not change), but which at the illocutionary level were given the shape of informative representations. The confessions subsequently came to be adopted as doctrinal propositions, which acquired a declarative, normative, or even polemical value, frozen at one stage of their historic evolution, and handed down to later generations in this stereotyped form.'
