IPA: /ˈkɪd.næp.iː/
KK: /ˈkɪdˌnæpi/
A person who has been taken away illegally by force or threat.
The police are working hard to find the kidnappee and bring them home safely.
Kidnappee → The word is formed from 'kidnap' (from 'kid' meaning child and 'nap' meaning to seize or take) and the suffix '-ee' (meaning a person who is the recipient of an action). The term 'kidnappee' refers to the person who is taken or seized, particularly in the context of abduction.
Think of 'kidnap' as taking someone, especially a child, and the '-ee' indicating the person who is taken. So, a kidnappee is the person who has been taken.
