(antacid)
neutralize acid
Etymology
'antacid' originates from Greek and Latin elements: Greek 'anti-' meaning 'against' and Latin 'acidus' meaning 'sour' or 'acid'.
'antacid' was coined in English in the late 19th century by combining the prefix 'anti-' with 'acid' to denote a substance acting against acid; the spelling has been standardized as 'antacid', though variants like 'antiacid' have appeared.
Initially it meant 'acting against acid (chemically)'; this core meaning has remained stable and is now used chiefly for medicines that neutralize stomach acid.
