The Dutch noun ramp , that may be related to this second English meaning means disaster.

I looked at the entry for ramp in a Dutch etymological dictionary, and they traced it back to Germanic word. I neglected to mention before that the Old French verb did not come from Latin but is thought to have been a borrowing from a Germanic language. The original was kramp (also in German and Dutch meaning 'convulsion'; cf. English cramp. The k got dropped in Burgundian and yielded ramp in French (link).

Ceci n'est pas un seing.
