(Interestingly, glamour shares an etymology with grammar. Spell and spelling.)
Not only was your wider point interesting, this digression was also really interesting. Makes sense though, the association between language and magic seems to be pretty common.
Interestingly “spelling” isn’t related to the magical version of the word “spell”:
In Middle English, spell meant “to mean” or “to signify,” which probably developed from Anglo-French espelier, itself from Middle High German spellen, meaning “to relate” or “to talk.” This spell, in modern English, then came to mean “to read slowly (letter by letter).”
Spell referring to magic incantation is of different origin. That word is strictly Germanic (from the noun spel) and refers to talk, storytelling, gossip, and a sermon. It also is the derivative of gospel (which translates to “good tale”) and is the source for the magical power and enchantment senses of spell.

Actually, they do share a potential root if the assumptions that they both share the Proto-Germanic root word, spellam, are correct.
so while they didn’t evolve one from the other, they did evolve from similar roots.
