受け入れる

to accept
受 — hand 爫 (top) + 冖 + hand 又 (bottom)
Originally a pictograph showing two hands passing an object (the middle 冖 represented a boat or tray) between them. It depicted the act of giving and receiving, so the character meant both 'to give' and 'to receive.' Later 授 was created with the hand radical 扌 to mean 'give,' leaving 受 to mean 'receive' or 'accept.'
入 — single pictograph, two slanting strokes
入 is a pictograph showing an arrowhead or pointed entrance, with two strokes converging downward to suggest something going inward. The original sense was 'to enter,' and it still carries that meaning today. It contrasts visually with 人 (person), where the strokes cross differently at the top.
