Yes, of course.

"Wanna ask if you can see what Emily's wings are like?"

"Sure. There's some actual birds around, I can compare."

Emily, when asked, is perfectly happy to cast her wings spell. She was already in magical girl form to futz with metal.

"They're definitely metallic. I don't think they exactly match anything else around but I'm not positive, I can't pay attention to everything in range at once."

"Steel. Might not be the exact same composition as any other steel around; lots of possible combinations of iron with stuff count as steel."

"What else is nearby and steel?"

She names several nearby steel objects.

"Huh. I think I can learn to distinguish the thing they have in common."

"Well, they probably have a lot in common, the differences are often as much in ratios as what the ingredients actually are."

"Yeah. What other metals are around?"

"Lots. Hang on a tic while I fetch a bunch of sculpture from my room?"

"Sure."

And Emily fetches an assortment of objects in an assortment of shapes and materials.

All of which Annie will happily learn the texture/ingredient combinations for.

Eee metallurgy nerding.

It's fun! Although sort of hard to take notes on. Annie is going to have to make up words.

Some of the things Annie's sense is picking up are similar enough to things perceptible via magnetism that Emily has made-up words to loan her!

That's handy! The languages power does not do neologisms but Annie can learn them the usual way.

It's really interesting that it doesn't do neologisms or conlangs. Maybe it's because they're not anyone's native language?

That could be it!

It could also potentially be because not enough people speak it, if it counts dead speakers for that purpose.

Plausible! What's some recently-invented word that is so new or jargony that no one has it 'natively' but which lots of people have picked up, can they think of one?

Hmm...Cinnamon roll? Bae? Lol? Yolo?

"...cinnamon roll is a food, other three I don't get."
