Morphology

hourglass = hour + glass (transparent) = hour + glass

The meaning is a literal combination of 'hour' and 'glass' (a glass device used to measure an hour), which learners can derive from the base words.

Etymology

Hourglass is made from two simple words, hour (a time of '60 minutes') and glass. It is a glass device where sand runs from the top to the bottom to measure an hour, so the name literally says what it does.
