Morphology

microsecond = second (transparent) = micro + second

The meaning is directly compositional: 'micro-' means one millionth and 'second' is a unit of time.

Etymology

The word microsecond begins with micro-, a Greek part that means 'small' and that you see in microscope and microphone, and it ends with second, the name for a unit of time. Put together, it means a very short time, 'one millionth' of a second, so scientists use it to measure very fast events.
