Morphology

subterraneous = subterranean (semi-transparent) = sub + terra + ous

The figurative sense 'hidden or concealed' is an extension of the literal 'beneath the earth' sense; the morphological parts are Latinate and only partly obvious to learners.

Etymology

Subterraneous comes from Latin parts sub- 'under' and terra 'earth', and by image it came to mean 'under the surface' or hidden. So a subterraneous feeling or motive is quietly 'under the surface' and not openly shown.
