Morphology

undermine = mine (transparent) = under + mine

The literal sense is a direct combination of 'under' + 'mine' meaning to hollow out beneath something. [Postprocessing: moved 'under' from base_words to prefix]

Etymology

The word undermine comes from under + mine, where mine means 'to dig a tunnel', just like miners dig in a mine. In old wars people dug tunnels under walls to make them fall, so to undermine something is to make a hollow under it and threaten its support.
