... or should that be 'Subundīs'?

I’ve always had a problem with the word ‘submarine’. It’s so called because the device goes beneath (Latin: sub) the sea (Latin: mare); but wouldn’t that be more appropriate for a vessel that burrows through the actual sea bed? A submarine actually only goes beneath the surface of the sea, not beneath the sea as such. The Latin for ‘waves’ is ‘undae’, so I think we should rename all submarines subundae at once.
