I was reading SO LN 3 and it said the following:

"Fairies• • •

Children favored by the gods. They were practically deities themselves. While not completely immortal, their lives could span many centuries. Like elves, they shared an affinity with magic. However, the fairies exceeded elves as magic users, possessing superior magic and the ability to perform miracles."

So from this, elves are not fairies.

And yet, elves are referred to as fairies by Bell, Mord, even the narrator from Sword Oratoria. Also there are elves with skills and magic that have fairy in their names or in the spell (ring of fairies, fairy cannon, fairy serenade, fairy anthem).

1. If elves are not supposed to be fairies, then what is the word that should be used for them in place of fairies? I can understand Bell and Mord calling elves 'fairies' in error or by preference, but that argument doesn't hold for the narrator of Sword Oratoria doing so.

2. If elves are supposed to be fairies then what is the word that should be used in the first paragraph for the 'children favored by the gods'? Are they supposed to be "spirits" instead?

3. If #2 is true, then what should the word '—Fairies' be instead in the following from LN 4? It would be weird to put '—Spirits', since it would be there twice:

""S-so that means the Crozzo family has• • •?"

"Yeah. We've got fairy blood in us."

—Fairies.

Nymphs, spirits, elementals, jinn• • •Their mysterious race has many names here on Earth. Their population is extremely small compared to the other races.

'The most loved of all the children.' 'Children of the gods.'

Humans and demi-humans have many stories about them, but the

one common thread is that fairies are the ones closest to the gods

themselves."
