Adoptive is the word for a parent (or a family) who has taken a child as their own through adoption — not the parent the child was born to. You almost always meet it in front of a family word: adoptive mother, adoptive father, adoptive parents, sometimes adoptive home.

Adoptive這個字 is the word for a parent (or a family) who has taken a child as their own through adoption是指透過收養把孩子當成自己孩子的父母（或家庭）——not the parent the child was born to而不是孩子的親生父母。 You almost always meet it in front of a family word你幾乎都會看到它放在家庭稱謂前面：adoptive mother養母、adoptive father養父、adoptive parents養父母，sometimes adoptive home有時候還有收養的家。

The legal, official flavour is still there, though families themselves may just say Mum and Dad. Though actually, English is fussy about which word sits where: the adult is adoptive; the child is adopted. People mix those two up all the time, and both can be said with love.

The legal, official flavour is still there法律上、正式的味道還在，though families themselves may just say Mum and Dad不過家人自己可能就只叫媽媽爸爸。 Though actually不過其實，English is fussy about which word sits where英文對這兩個字用在哪裡很講究：the adult is adoptive大人用adoptive，the child is adopted小孩用adopted。 People mix those two up all the time大家常常把這兩個字搞混，and both can be said with love但兩個字都可以帶著愛說出口。

You would not use adoptive for taking up an idea or a habit; that is just adopt.

You would not use adoptive不會用adoptive，for taking up an idea or a habit來說接受一個想法或習慣這件事；that is just adopt那就只是adopt。
