Unspeakably → It is formed from "un-" (meaning not) and "speak" (from Old English "specan", meaning to say or talk) and "-ably" (meaning in a manner that can be). The word "unspeakably" means in a manner that cannot be expressed in words or is beyond description.
Think of 'not' ('un-') being combined with 'saying' ('speak') and 'in a manner' ('-ably'). This helps you remember that 'unspeakably' refers to something that cannot be adequately expressed.
