Morphology
subterraneous = subterranean (semi-transparent) = sub + terr + aneous
The word is best understood as a rare variant built on the same 'under the earth' base, but the learned stem and ending are not fully obvious to average learners.
Etymology
Subterraneous comes from Latin parts sub- 'under' and terra 'earth', the same sub- you see in subway and the terra in terrain. So it means something that is 'under the earth', like pipes, tunnels, or underground water.
