覚え方のコツ Memory Tip
rearing は動詞 rear「育てる・飼育する」に -ing を付けた形で、語末の r を重ねずそのまま加えます。名詞では chicken rearing、calf rearing、child-rearing のように、成長するまで継続して世話をする営みを表します。一時的な care より長期的な養育を意識しましょう。
Connect rearing with its base verb rear, meaning “to raise and care for a young person or animal.” The form is made simply by adding -ing, without doubling the final r. Think of long-term, practical responsibility: chicken rearing requires water and housing, calf rearing requires feeding, and child-rearing involves care and guidance over many years. This distinguishes rearing from care in general, which may be temporary. Common combinations such as animal rearing, poultry rearing, and child-rearing make the noun’s meaning easy to recognize.

rearing の語源・成り立ち Etymology
古英語「rǣran（立たせる）」に由来し、語源的には「rise（立つ）」の使役形です。子や動物を「立ち上がらせて一人前にする」イメージが転じ、「飼育」を指すようになりました。同根語にarise（起こる）とrise（上がる）があります。
Rearing is formed from rear plus the suffix -ing. The verb rear comes from Old English rǣran, meaning “to raise, build up, or cause to rise,” and is historically related to rise. Its physical sense of making something stand developed into the sense of bringing a young animal or child toward maturity. As a noun, rearing now refers to that continuing process of feeding, protecting, and raising.
