adjourn (v.)
mid-14c., ajournen, "assign a day, fix a day" (for convening or reconvening of an organized body), from Old French ajorner (12c.) "meet" (at an appointed time), from the phrase à jorn "to another day, to a (stated) day," from à "to" (see ad-) + journ "day," from Latin diurnus "daily," from dies "day" (from PIE root *dyeu- "to shine").
The notion is of setting a date for re-meeting. The meaning "close a meeting" (with or without intention to reconvene) is from early 15c. The sense of "go in a body to another place" (1640s) is colloquial.
The English word has had the -d- since 16c., but the spelling is unetymological, as the compound apparently is not from Latin; Middle French also occasionally has adjourner, but this was rejected in Modern French. Related: Adjourned; adjourning.
