Glamour

[Alneyan]

Glamour is not of direct Latin origins, unlike virtually any other "our" name in the English language (ardour, valour, honour...). Incidentally, I gather it is why glamour is by far the most widely spelling of the name, and "glamor" is a rare spelling, even in American English, while honor and honour are both common spellings.

The most common etymology I found was from Scots, where glamour appears to be a transformation of "grammar", and was literally a magic spell, especially one affecting the sight. Glamer was an alternate spelling for this glamour. Icelandic has similar words, connected to a weak sight, the moon, and a ghost, but I am unable to check that (I couldn't speak Icelandic if my life depended on it).

So, I gather glamour is actually a very corrupted word coming straight from Greek (through Latin and French), sharing a connection with grammar (French grammaire). I guess grimoire comes from the same path too.
