tend (v.1)

"to incline, to move in a certain direction," early 14c., from Old French tendre "stretch out, hold forth, hand over, offer" (11c.), from Latin tendere "to stretch, extend, make tense; aim, direct; direct oneself, hold a course" (from PIE root *ten- "to stretch"). The PIE root produced two Latin verbs, tendere "to stretch" and tenere "to hold, grasp" (source of tenacity, etc.), perhaps from inflected forms in the one PIE verb. Both Latin verbs have past participle tentus.

tend (v.2)

"attend to," c. 1200, a shortening of Middle English atenden (see attend).
