Euthanasia is when someone who is very ill, and close to deathEuthanasia（安樂死）指的是，當一個人病得很重、已經接近死亡的時候 is killed on purpose被故意結束生命 so they will not keep suffering好讓他們不用繼續受苦。In the strict sense在嚴格的意義上 a doctor or another person does the last act that ends the life是由醫生或其他人執行結束生命的最後那個動作。
Countries argue about whether this should be legal, and under what rules: the dying person must usually ask for it, doctors must agree the illness cannot be , and there are checks so nobody is pushed. Some places allow it; many, including Taiwan, do not treat it as a normal medical choice.
Countries argue fiercely about whether this should be legal, and under what rules各國對於這件事是否應該合法，以及該有什麼規則，爭論得很激烈 : the dying person must usually ask for it：通常必須是快要死去的人自己提出要求 doctors must agree the illness cannot be cured醫生必須認定這個病無法治癒 and there are checks so nobody is pushed而且要有審查機制，確保沒有人被逼迫。Some places allow it有些地方允許安樂死 many, including Taiwan, do not treat it as a normal medical choice許多地方，包括台灣，並不把它當成一般的醫療選項。
People also stretch the word in debate. Turning off a machine that is only keeping the body going, or giving strong pain medicine that may also life, sit in a grey area some speakers still call euthanasia and others carefully do not.
People also stretch the word in debate人們在辯論時也會延伸使用這個字。Turning off a machine that is only keeping the body going關掉只是在維持身體運作的機器 or giving strong pain medicine that may also shorten life或給予可能也會縮短生命的強效止痛藥 sit in a grey area都處在一個灰色地帶 some speakers still call euthanasia and others carefully do not有些人還是稱之為euthanasia，有些人則刻意不這麼稱呼。
It is a formal, heavy word — hospital, law, and newspaper language, not casual chat. It is not the same as suicide (the person ending their own life) and not the same as murder (killing out of hate or gain), though the law in each country draws those lines differently. When English speakers talk about a very sick pet, they more often use the verb than this noun.
It is a formal, heavy word這是一個正式、沉重的字 — hospital, law, and newspaper language, not casual chat——醫院、法律和報紙上的用語，不是隨口聊天會說的話。It is not the same as suicide (the person ending their own life)它跟suicide（自殺，指自己結束自己的生命）不一樣 and not the same as murder (killing out of hate or gain)也跟murder（謀殺，指出於仇恨或利益而殺人）不一樣 though the law in each country draws those lines differently不過每個國家的法律劃分這些界線的方式都不太一樣。When English speakers talk about a very sick pet當英語使用者在談一隻病得很重的寵物時 they more often use the verb euthanize than this noun比較常用動詞euthanize，而不是這個名詞。
組成From Ancient Greek euthanasía: eu- “good” + thánatos “death” — first used in English in 1606. The pieces still match the idea: a death meant to be gentle.
