Prosthetic names an artificial body part that takes the place of a missing one — a leg, a tooth, a hand — the same idea as prosthesis. In careful medical talk it is first an adjective (a prosthetic leg, a prosthetic tooth), and people also use it as a noun, especially for a limb: “she wears a prosthetic.” That noun use is a shorter, more everyday shape of the same meaning.

Prosthetic prosthetic names指的是 an artificial body part that takes the place of a missing one取代掉一個缺失部位的人工身體部位 — a leg, a tooth, a hand一條腿、一顆牙齒、一隻手 — the same idea as prosthesis跟prosthesis義肢/義體是同一個概念。In careful medical talk在謹慎的醫學用語裡, it is first an adjective它首先是一個形容詞 (a prosthetic leg, a prosthetic tooth)（a prosthetic leg義肢腿、a prosthetic tooth義齒）, and people also use it as a noun而人們也會把它當名詞用, especially for a limb尤其是指肢體的時候: "she wears a prosthetic."『she wears a prosthetic她戴著義肢』。That noun use is a shorter, more everyday shape of the same meaning那個名詞用法，是同樣意思比較簡短、比較日常的樣子。

Film workers stretch it further: “prosthetics” can mean a fake nose, ear, or piece of skin built for an actor. That is still an added body part, but for a story, not for walking.

Film workers電影工作者 stretch it further把這個字用得更廣: "prosthetics" can mean『prosthetics特效化妝義體』可以指 a fake nose, ear, or piece of skin built for an actor為演員做的假鼻子、假耳朵，或一片假皮膚。That那 is still an added body part仍然是一個附加上去的身體部位, but for a story, not for walking只是為了說故事，而不是為了走路。

Though actually, in real conversation the adjective and the noun keep mixing, and that is normal.

Though actually不過其實, in real conversation在真實對話裡 the adjective and the noun keep mixing形容詞和名詞的用法一直混著用, and that is normal而這是正常的。
