Usage notes

The main sense of "synonymous" (#1) can be considered polysemous. Since synonymy is relative, linguists distinguish between absolute synonymy and partial synonymy, and many consider synonymy as a scale, meaning that some synonyms are more synonymous than others. For more information, see the Usage notes section of synonymy.
