Root Explanation

Atwitter originates from the combination of "a-" (a prefix meaning in a state of) and "twitter" (from Middle English *twiteren*, meaning to chirp or make a light, rapid sound). The word "atwitter" describes a state of excitement or agitation, akin to the rapid, light sounds made by birds.

Memory Tip

Think of being 'in a state of' excitement ('a-') like the quick, light sounds ('twitter') that birds make. This helps you remember that 'atwitter' means being in a state of excitement or agitation.
