kid-friendly

the compound adjective 'kid-friendly' is a modern formation, blending the informal noun 'kid', meaning child, with the productive suffix '-friendly'. the term 'kid' itself has a fascinating journey, originating from old norse 'kið', meaning a young goat, which entered middle english with the same meaning before its sense broadened colloquially to refer to a child. the suffix '-friendly' evolved from the old english adjective 'frēondlīc', meaning 'like a friend'. in contemporary usage, '-friendly' has become a highly productive combining form, indicating suitability or ease of use for a specified group or purpose. thus, 'kid-friendly' logically denotes something characterized by being suitable or safe for children, extending the concept of amicability to inanimate objects and environments.
