sunscreen
UK: ˈsʌnskriːn | US: ˈsʌnskriːn
n. a lotion, spray, or gel applied to the skin to protect it from the sun's ultraviolet rays.
The word "sunscreen" is a compound of "sun" (from Old English sunne, meaning the celestial body) and "screen" (from Middle Dutch scherm, meaning a shield or barrier). It emerged in the early 20th century as a term for products designed to block or filter sunlight, reflecting its literal function as a "shield against the sun." The morphemes combine transparently, making the word easy to decode for learners.
