unwonted

adj

Etymology: From un- + wonted. Redundant in form, as wont is by itself historically the participle adjective. Largely displaced earlier unwont.

1. Not customary or habitual; unusual; infrequent; strange.

   “Be of comfort; / My father's of a better nature, sir, / Than he appears by speech: this is unwonted, / Which now came from him.”

   “After the first flutter of conscious delight which his entrance had caused, she was able to talk to him cheerfully, and her spirits rose with the unwonted enjoyment.”

2. Unused (to); unaccustomed (to) something.
