Unstring → It is formed from "un-" (meaning not or opposite of) and "string" (from Old English "streng", meaning a cord or thread). The word "unstring" means to remove the strings from something, effectively making it not strung or without strings.
Think of 'un-' meaning not, and 'string' referring to a cord or thread. This helps you remember that 'unstring' means to take away the strings.
