Morphology

subglacial = glacial (transparent) = sub + glaci

'sub-' (under/beneath) combined with 'glacial' (relating to a glacier) yields the clear meaning 'beneath a glacier'.

Etymology

Subglacial breaks into sub- meaning 'under' and glacial from glacier meaning 'ice'. So, Subglacial describes something 'under the ice', which is why scientists use it for rivers, lakes, or land hidden below a glacier.
