I’ve quite often seen, in manuscript facsimilies and early printed books, forms which by the normal grammatical/lexical understanding of Latin should have final -m drop this; mostly they seem to be written with a macron or tilde over the preceding vowel. Occasionally I’ve seen it in the interior of words too (e.g. two of the MSS in Cecil Clementi’s Pervigilium Veneris have ‘cras amet qui nÅ©quã amauit’ while the other has numquã). The most obvious explanation is that this represents nasalisation - I’m curious about its history, particularly when it was first used, and if it was normal in some areas and not others, but not being a palaeographer I’m not quite sure where to look, and I wondered if anyone here knew anything about it or could point me in the right direction. Many thanks.
