Morphology

nonsubmergible = submergible (transparent) = non + submerge + ible

Formed by a straightforward negation prefix 'non-' added to an adjective meaning 'able to be submerged', so the negative meaning is directly predictable.

Etymology

Nonsubmergible breaks into non- 'not', sub- 'under', merg 'to sink', and -ible 'able'. So a nonsubmergible object is 'not able to be sunk' and will stay on the surface of the water.
