Usage

What does adoption mean? Adoption is the process of adopting another parent’s child—taking them into one’s custody, typically in a formal, legal way in order to permanently act as their parent or guardian. This most commonly involves an adult couple or a single adult adopting and raising a child who is no longer in the custody of either of their birth parents (biological parents), such as in cases where they have died or are otherwise unable to care for the child. This sense of adoption can also be used in reference to adopting an animal as a pet, such as from an animal shelter. The word is especially used this way when the animal had a previous caretaker. Adopt and adoption have many other more general meanings. Most generally, adopt means to choose or take as one's own. It can also mean to accept something or vote to approve it. In all cases, adoption is the act or process of adopting, or the state of having adopted. The adoption of a tradition or religion involves making it one’s own. The adoption of a plan involves approving it and acting according to its steps. Similarly, the adoption of a law involves the formal vote to approve it and the steps taken to follow and enforce it. Example: We’ve found an agency that will help us through the process of adoption.

Explanation

Adoption is the act of taking something on as your own. Adoption usually refers to the legal process of becoming a non-biological parent, but it also refers to the act of embracing ideas, habits, or free kittens. Adoption comes from the Old French word adoptare, meaning "to chose for oneself.” Feel like adding an option? Try adoption. Adoption is the noun form of adopt, so it not only refers to legally taking another person into your family, it can be any time you take something on as your own. If you start dressing like a friend, that's an adoption of your friend's style. If that friend wears micro-miniskirts, your parents might put you up for adoption.
