Answer

Existing or situated beneath the earth's surface
The word 'subterranean' is formed by combining the prefix 'sub-' (meaning under or below) with the Latin root 'terra' (meaning earth or ground). Therefore, 'subterranean' describes something existing or situated beneath the surface of the earth.

Step-by-Step Solution

1
Isolate and identify the prefix of the target word.
The word begins with the directional prefix 'sub-', which denotes 'under,' 'below,' or 'beneath.'
Prefixes establish critical spatial and relational orientation in morphological word analysis.
2
Analyze the remaining root and suffix elements.
The root 'terra' means 'earth' or 'land,' and the adjectival suffix '-an' indicates belonging to or characteristic of.
Combining root and affix definitions allows for precise structural deduction.
3
Synthesize the morphological components to select the definition.
'Sub-' (under) + 'terra' (earth) + '-an' (pertaining to) = situated under the earth.
Matching the synthesized meaning to the choices confirms the correct definition without ambiguity.
