To make something sweeter or more pleasant in taste or character (archaic term).
From Latin 'addulcis,' combining 'ad-' (to) with 'dulcis' (sweet), literally meaning 'to make sweet.' This word is largely obsolete in modern English.
This delightfully obscure word disappeared from common English around the 16th century, but its root 'dulcis' survives in English words like 'dulcet' (sweet-sounding) and 'dulcimer' (musical instrument).
