Etymology
The word 'whitecap' is a transparent English compound formed from two native Germanic elements. 'White' descends from the Proto-Germanic 'hwītaz', itself from the Proto-Indo-European root 'ḱweyt-', meaning 'to shine' or 'bright', which naturally evolved to denote the color of pure light. 'Cap' originates from the Late Latin 'cappa', meaning a hooded cloak, which entered Old English. The compound logically and visually describes a wave whose crest is covered with a 'cap' of white foam, a straightforward metaphorical construction in English for a natural phenomenon.
