Among the different śabda - vyāpāras or the functions of a word to convey the sense, vyañjana is the third category of relation of word and meaning. This tertiary power of word is also known as suggestion. Writers on poetics (Rhetoricians) and Grammarians accept this third type of word relation in the form of Vyañjana (Suggestion) and it is entirely different from Śakti (Abhidha) and Lakṣaṇa.
