|Meaning: Differs from the reference object (reference). The object does not have to exist for an expression to have a meaning. Words are not related to objects in a one-to-one correspondence. There is an important distinction between word meaning and sentence meaning. See also use theory, sentence meaning, reference, truth.|

Frege: sense/meaning - GeachVsRussell: false equivalence with "means"/"denotes" (refers to) in Principia Mathematica - seeming parallel: a description contains "meaning" (Sinn) as a component, but not on this sense but about the objects. The description denotes.
Signifiying expression/Russell: general term with a prefix, all, some, etc.
Meaning/Principia Mathematica: two phrases mean the same thing when they maintain the same assumption - Signify/Frege: two sentences mean the same when they have both the same truth value.
Incomplete symbol/Russell/late: certain descriptions have no meaning.
GeachVs: this is misleading – rather: we do not need a single entity that corresponds to a specific description – E. g "There is a King…".
