Adjournment
The historical practice of pausing an unfinished tournament game to resume at a later time, using a sealed move.
Adjournments were standard before fast digital analysis engines made secret home preparation between sessions too significant an advantage, and have been almost entirely phased out of elite competition today.
Etymology
Adjournment entered English in the mid-15th century as ajournement, “act of postponing or deferring (a court, assembly, etc.),” from Old French ajornement, whose underlying phrase à jorn means “to another day” — the notion is of setting a date for re-meeting. Chess simply borrowed the legal-parliamentary word for its own practice of suspending a game with the intention to finish it later, once very common in high-level competition but mostly abandoned due to the advent of computer analysis. The first World Chess Championship not to use adjournments was the Classical World Chess Championship 1995, and the last one to use them was the FIDE World Chess Championship 1996. No source consulted gives a first-use date for the practice.
