IPA: //ˌæn.tiˈsmʌt//
KK: /æntiˈsmʌt/
Opposed to indecent or sexually explicit material.
The antismut campaign aims to promote a more family-friendly environment online.
The word 'antismut' is formed from 'anti-' (meaning against) and 'smut' (from Old English 'smyttan', meaning to smear or stain). The term refers to something that acts against or prevents smut, which is a type of fungal disease affecting plants.
Think of 'anti-' meaning against, and 'smut' referring to a stain or blemish — so 'antismut' means something that works against stains or blemishes.
