Full Idea
We can define, it would seem, a strong synonymy relation for single words by them being interchangeable salva veritate.

'Salva veritate' means truth-preserving
Gist of Idea
Single words are strongly synonymous if their interchange preserves truth

A Reaction
This is a first step in Quine's rejection of synonymous sentences. He goes on to raise the problem of renate/cordate. Presumably any two word types can have different connotations, and hence not always be interchangeable - in poetry, for example.
