Mellifluous literally means ‘flowing like honey’.
Applied to the spoken or written word, it’s complimentary, saying it’s pleasantly rhythmic.
Strangely, the Anglo-Saxon honey-tongued has negative connotations – persuasiveness with treachery behind it.
But mellifluous actually sounds mellifluous, as do other words with ‘m’ and ‘l’ in them, like lemon, and melon, and honey in Latin-based languages (mel, miel, miele …)
Long live the melody of language.
