In Linguistics, 'utterance' is often used for the action of pronouncing orally a sentence, but philosophers tend to also include writing, signing, and other modes of language use, and for the action of using a sub-sentential expression.
We cannot say that a given apparent name should be replaced by a synonymous term for a complex since Wittgenstein denies that sub-sentential expressions have sense (3.3).
The juxtaposition of these two claims suggests that the context principle is invoked as the ground for rejecting senses for sub-sentential expressions.
Another, more concrete, possibility is that Wittgenstein simply accepted the arguments Russell had given in "On Denoting" for rejecting senses for sub-sentential expressions.
The issue of what counts as a complete (grammatical) sentence opposed to a sub-sentential complex expression pertains to syntax, rather than to semantics or pragmatics.
Raffaella Zanuttini began working in micro-comparative syntax by studying minimal variations in the expression of sentential negation within the Romance language family, including many non-standard varieties spoken in Northern Italy (see Negation and Clausal Structure: A Comparative Study of Romance Languages, Oxford University Press).
Epistemic modality is expressed by sentential adverbs which take an entire proposition as their complement.
On the first, linguistic level, we deal with proper sentential forms, i.e., with expressions containing variables, which become sentences (and express propositions) after appropriate substitutions are made.
Aristotle distinguishes things that have sentential unity through a combination of expressions ('a horse runs') from those that do not ('horse'runsuns'); the latter are dealt with in the Categories (the title really means 'predications'[1]).
Methods for stimulating creativity are strongly based on generating ideas in a sentential manner, while in product design visual expression is a strong device for stimulating creativity.
The sentential form [Satzform] is a linguistic expression obtained from a proposition, or rather from a sentence which expresses it, by considering some of its parts variable.
