Word: Bathing Cap
Definition: A bathing cap is a tight-fitting cap that you wear on your head while swimming. Its main purpose is to keep your hair dry and to protect it from chlorine or saltwater.
In competitive swimming, athletes often wear streamlined bathing caps to reduce water resistance and improve their speed in the water.
While "bathing cap" specifically refers to the swim accessory, the word "cap" can also refer to other types of headwear, like a baseball cap or a hat.
There are no specific idioms or phrasal verbs related directly to "bathing cap." However, you might hear phrases like "keep your head above water," which means to manage or survive difficult situations, but this is not related to the bathing cap itself.
