To adopt another person means to legally take that individual into one's family as if they were born to it. It is a legal process where an adult assumes the parental rights and responsibilities for another person, making them their child. This can be done through various ways such as fostering or adoption. The main purpose of adopting someone else’s child is usually because the biological parents are unable to care for them properly, so a new family takes over that responsibility. Adoption provides a stable and loving home environment for children who may not have had one otherwise.
