Morphology

subsea = sea (transparent) = sub + sea

The prefix 'sub-' clearly indicates 'under' or 'below', making the meaning of 'subsea' as 'under the sea' straightforward.

Etymology

Subsea comes from the prefix sub- meaning 'under' and the common word sea, so it literally means 'under the sea'. That's why subsea is used for pipes, cables, and work that happen below the sea, just like a submarine goes under the sea.
