After 200 years of preachment the following observations may be made: the position of only in standard spoken English is not fixed, since ambiguity is avoided through sentence stress; in casual prose that keeps close to the rhythms of speech only is often placed where it would be in speech; and in edited and more formal prose only tends to be placed immediately before the word or words it modifies. III. conjunction 1. a. with the restriction that; but Example: you may go, only come back early b. and yet; however Example: they look very nice, only we can't use them 2. were it not that; except Example: I'd introduce you to her, only you'd win her — Jack London
