Water wings are two small bags of air that you blow up and push onto a child's upper arms, one on each side, so that the child floats while learning to swim. They are usually bright orange or yellow plastic. The word is almost always plural — you wear two, so you say "water wings", the way you say "glasses" or "shoes". Most people write it as two words; you will also see it as one word or with a hyphen. The word belongs to children and to parents: swimming pools, beaches, holidays. It carries a feeling of being small and not yet able — which is why grown-ups use it as a picture for anything that supports a beginner. "You can take the water wings off now" means "you can do this on your own now". Said to an adult, that is teasing, and it can sting a little, so use it gently. British speakers say water wings most readily. In the US you will often hear "floaties" for the same thing, and that word covers other inflatable arm bands and rings too. If you are talking to Americans, floaties is the safer word.
