I'm a little stuck... Click here to teach me more about this clue!

'they' is the definition.
Both the answer and definition are plural nouns.

'any salts' can be anagrammed to 'ANALYSTS'.
Though, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for analysts that I've seen before include "shrinks" , "psychiatrists" .)
