To be Taxallan enemies I guess. Dryden.

Syn. -- To conjecture; suppose; surmise; suspect; divine; think; imagine; fancy. -- To Guess, Think, Reckon. Guess denotes, to attempt to hit upon at random; as, to guess at a thing when blindfolded; to conjecture or form an opinion on hidden or very slight grounds: as, to guess a riddle; to guess out the meaning of an obscure passage. The use of the word guess for think or believe, although abundantly sanctioned by good English authors, is now regarded as antiquated and objectionable by discriminating writers. It may properly be branded as a colloguialism and vulgarism when used respecting a purpose or a thing about which there is no uncertainty; as, I guess I 'll go to bed.

This is the place, as well as I may guess. Milton.

A poet must confess
His art 's like physic -- but a happy guess. Dryden.
