Morphology

underlie = lie (transparent) = under + lie

Formed by productive prefixation under- + lie meaning 'to lie under'; the abstract sense 'be the basis' is a direct metaphorical extension that learners can derive.

Etymology

Underlie breaks into under meaning 'below' and lie meaning 'to rest or be placed'. So, if something underlies another thing, it is 'below' it and forms its base or hidden cause.
