Made less intense, extreme, or violent; brought within reasonable limits or kept under control. Describes something that has been tempered or made more balanced.
From Latin 'moderatus', past participle of 'moderari' meaning 'to control, guide, restrain' from 'modus' (measure, limit). The word evolved from the idea of keeping within proper measure or bounds.
A moderator in online forums does exactly what the word suggests - they keep discussions within reasonable bounds! Even 'modern' comes from the same root, originally meaning 'just now, within measure' - not too old, not too new, but just right.
