Minor theorems are often called propositions. Theorems which are not very interesting in themselves but are an essential part of a bigger theorem's proof are called lemmas. (mathematics, colloquial, nonstandard) A mathematical statement that is expected to be true. (logic) A syntactically correct expression that is deducible from the given axioms of a deductive system. ==== Synonyms ==== (proven statement): lemma, proposition, statement, see Thesaurus:theorem (unproven statement): conjecture, hypothesis See also Thesaurus:statement ==== Hyponyms ==== ==== Holonyms ==== theory ==== Derived terms ==== ==== Related terms ==== ==== Translations ==== ==== See also ==== ==== Further reading ==== theorem on Wikipedia.Wikipedia === Verb === theorem (third-person singular simple present theorems, present participle theoreming, simple past and past participle theoremed) (transitive) To formulate into a theorem. ==== Further reading ==== “theorem”, in Webster’s Revised Unabridged Dictionary, Springfield, Mass.: G. & C.
