Morphology

assure = sure (semi-transparent) = a + sure

Built from 'sure' with a causative/verb-forming prefix; meaning 'make certain/guarantee' is related to 'sure' though specific collocational uses (e.g., assure vs ensure/insure) may be unpredictable.

Etymology

Assure comes from the Latin root securus, meaning 'safe' or 'secure', and is related to the familiar words secure and ensure. So to assure something is to 'make it certain' or guarantee it, which is why the word can mean to make sure something will happen.
