presolar positive

Morphology

presolar = solar (semi-transparent) = pre + solar

The prefix 'pre-' clearly means 'before', but the full scientific sense specifically means 'before the formation of a solar system', which is more specialized than a simple everyday reading of 'before solar'.

Etymology

The word presolar is made of pre- ('before') and solar ('sun'), so it means 'before the sun' or 'from before a solar system formed.' That's why tiny grains older than our sun are called presolar.
