"an item on an agenda;" see agenda.

1760, from American Spanish, "an estate or ranch in the country," from Spanish hacienda "landed estate, plantation," earlier facienda, from Latin facienda "things to be done," from facere "to do" (from PIE root *dhe- "to set, put"). For noun use of a Latin gerundive, compare agenda. The owner of one is a hacendado.

The change of Latin f- to Spanish h- is characteristic; compare hablar from fabulari, hacer from facere, hecho from factum, hermoso from formosum. Confusion of initial h- and f- was common in 16c. Spanish; the conquistador is known in contemporary records as both Hernando and Fernando Cortés.

mid-15c., "(something) to be remembered," a note of something to be remembered for future reference or consideration, from Latin memorandum "(thing) to be remembered," neuter singular of memorandus "worthy of remembrance, noteworthy," gerundive of memorare "to call to mind," from memor "mindful of" (from PIE root *(s)mer- (1) "to remember").

Memorandum, A terme used when wee write any thing we would not forget. [Cockeram, English Dictionarie, 1623]

"Used originally as mere Latin, and usually abbreviated mem., to introduce a note of a thing to be done" [Century Dictionary]; by 1540s it came to mean the note itself. The Latin plural is memoranda. Compare also agenda.
