Morphology

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

Formally built from the adjective 'sure' with a prefix meaning 'to make' or 'cause', but the verb's usage and nuance (esp. reassuring a person) may not be fully predictable for all learners.

Etymology

Assure comes from the Latin root securus, which meant 'safe' or 'secure' and is the same root as the words secure and ensure. So to assure someone is to tell them something confidently to make them 'sure' and remove their doubts.
