Reconstruction:Proto-Celtic/sanestos

Etymology
Of unclear origin. The usual comparison to (from ) is formally very unlikely, as proto-Celtic *sw- regularly corresponds to chw- in Welsh, yet the Welsh descendant of this root features an h- instead. Perhaps from (which would semantically shift to "advice" > "whisper"), from ; however, this is semantically bold and makes an assumption that "advice" was the original meaning.

Noun

 * 1) secret, whisper
 * 2) advice, counsel
 * 3) history
