Unkind → It is formed from "un-" (meaning not) and "kind" (from Old English "cynd", meaning nature or character). The word "unkind" means not having a kind nature or character, indicating a lack of kindness.
Think of 'not' ('un-') being added to 'kind' — this helps you remember that 'unkind' means lacking kindness.
