Morphology

prolong = long (semi-transparent) = pro + long

The connection to 'long' is fairly clear, but 'pro-' does not function as a productive modern English prefix meaning 'make longer' for most learners.

Etymology

The word prolong comes from Latin parts pro- 'forward' and longus 'long', and you can see the same 'long' in the English word long. So, to prolong something is like pushing it forward in time to make it last longer.
