- Let us consider ‘my dog is asleep on the floor’ again. Frege thinks that this sentence can be analyzed in various different ways. Instead of treating it as expressing the application of __ is asleep on the floor'' to ''my dog'', we can think of it as expressing the application of the concept
''my dog is asleep on __''
to the object
''the floor''
(see Frege 1919). Frege recognizes what is now a commonplace in the logical analysis of natural language. ''We can attribute more than one logical form to a single sentence . Let us call this the principle of multiple analyses . Frege does not claim that the principle always holds, but as we shall see, modern type theory does claim this.

Usage notes
Principle is always a noun ("moral rule"), but it is often confused with (principal), which can be an adjective ("most important") or a noun ("school principal"). Consult both definitions if in doubt. Incorrect usage: * He is the principle musician in the band * She worked ten years as school principle A mnemonic to avoid this confusion is "The principal'' alphabetic ''principle'' places ''A'' before ''E ".Synonyms
