- sustain (v.)
- c. 1300, "give support to," from stem of Old French sostenir "hold up, bear; suffer, endure" (13c.), from Latin sustinere "hold up, hold upright; furnish with means of support; bear, undergo, endure," from sub "up from below" (see sub-) + tenere "to hold" (see tenet). Meaning "continue, keep up" (an action, etc.) is from early 14c. Sense of "endure without failing or yielding" is from c. 1400. Related: Sustained; sustaining.
