What word-class does ALL belong to? The evidence seems to suggest that it is a determiner-like pronoun. Like other determiners it allows a common noun as its complement (all students), and cannot itself combine with a preceding determiner or adjective (*the/good all students), but it is unlike most determiners in various respects:
(1) They have all/each written an essay.
This list of exceptional features makes one wonder whether ALL really is a pronoun, but on balance this seems the simplest analysis. One possible conclusion is that it belongs to a mixed category, pronoun and adjective. (This would explain why it can be modified by an adverb.) This doesn't help with the floating-quantifier use, which looks like a purely idiosyncratic fact which it happens to share with EACH.
