人工受孕

人 = 丿 + ㇏ : Mnemonic symbol: Neanderthal Man (人). Robinson Crusoe (r-) is looking for snacks in the encampment's kitchen (-en2) when he suddenly spots Neanderthal Man (人). Neanderthal Man offers him a banana (丿), but Robinson Crusoe doesn't trust the present and pokes it with a finger (㇏).

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam. In front of the engine ((e)ng1), Gitta Giraffe (gu) is doing some hard work: She's stacking a capacitor (二) on a dinosaur bone (丨) on a capacitor (二). She's not very successful, but then she gets the idea to use steel beams (工) as support.

受 = 爫 + 冖 + 又 : Mnemonic symbol: 受 is often used in a negative sense, when something bad happens to the speaker. I thus represent 受 by a stretcher, which is used to transport injured persons.

受 = 爫 + 冖 + 又 : Sherlock Holmes lost a boxing fight in the outhouse, and he's lying on a stretcher in the bathroom now. He still has his boxing gloves on. He got beaten so badly that is opponent was even able to shave his head with an electric razor. Nobody had a cover at hand, so he's just provisionally covered with a cooking top.

孕 = 乃 + 子 : Yu the Great (yu) has been dating a poltergeist (乃) recently in the encampment's bathroom ((e)n4) and now she has to tell him that she is pregnant (孕) with his egg (子).
