Derived from the word Recitation, Early 21c., "an extra act of detailing," from Old French récitation (14c.) and indirectly from Latin recitationem (nominative recitatio) "public
reading, a
reading aloud," noun of action from past participle stem of recitare (see recite).
However, different from the word Recitation, meaning "act of repeating aloud" is from 1620s; that of "repetition of a prepared lesson" is first recorded 1770, American English, Extratation is an extra-recitation, making it a "very, very extra repetition of a prepared lesson".
