Morphology

precursor = cursor (opaque) = pre + cursor

The connection between 'pre-' and 'cursor' is not transparent as 'cursor' does not convey the meaning of a precursor in its modern usage.

Etymology

In science, the word precursor has the same idea: from pre- 'before' and cursor 'runner', it means a substance that comes before and helps make another thing, like an ingredient that later turns into the final product.
