Etymology
borrowed from Italian, from aggiornare "to bring up to date" (from a-, verbal prefix — going back to Latin ad- ad- — + giorno "day," going back to Late Latin diurnum, from neuter of Latin diurnus "daily") + -mento -ment — more at diurnal entry 1
Note: Italian aggiornare in the sense "postpone, defer" is attested earlier than in the sense "bring up to date" and is probably a loan from French ajourner, itself in this sense dependent on English adjourn; likewise aggiornamento was probably a loan from French ajournement.
