接受 = accept something with grace 接 has many meanings: to receive / to answer (the phone) / to meet or welcome sb / to connect / to catch / to join / to extend / to take one's turn on duty / to take over for sb Therefore you cannot shorten it.

these two words have different meanings. the word 接 means u raise(i think u can understand,i don't know what i should use here) your hand , and get someone's something. For example, u give me an apple, and 我接过来这个苹果。 接受 means u 接 something by heart, some people give u money, u received them but u don't accept them. 我接了钱，但是我心里不接受。 can u understand?

as in English "take in；accept；receive；adopt" means you agree of something or agree to do something. e.g."他接受了这个结果“ “我接受了他的邀请” It seldom be shorten as “接”，unless you say “接电话”——pick up the phone

I think Jeff has a great understanding of them.So you couldn't do so.

it is different. eh..i don't know how to say.
