Origin and history of suscipient

"capable of admitting, capable of being passively affected," c. 1600, from Late Latin susceptibilis "capable, sustainable, susceptible," from Latin suscept-, past-participle stem of suscipere "to take, catch, take up, lift up; receive, admit; submit to; sustain, support, bear; acknowledge, accept," from sub "up from under" (see sub-) + capere "to take" (from PIE root *kap- "to grasp").

"[C]ommonly with of before a state and to before an agency" [Century Dictionary]. Susceptive in the same sense is recorded from early 15c. Specifically as "capable of emotional impression, sensitive mentally" by 1709. Related: Susceptibly; susceptibleness.
