Quote from ‘Letters to Lady Welby’

In regard to its relation to its signified interpretant, a sign is either a Rheme, a Dicent, or an Argument. This corresponds to the old division Term, Proposition, & Argument, modified so as to be applicable to signs generally. [—] A proposition as I use that term, is a dicent symbol. A dicent is not an assertion, but is a sign capable of being asserted. But an assertion is a dicent. [—] I define a dicent as a sign represented in its signified interpretant as if it were in a Real Relation to its Object. (Or as being so, if it is asserted.)
