Que? (adjective pronouns)

[Molly]

Can anyone here please make head or tail of this passage?

"ADJECTIVE PRONOUNS.

131. Most of the words how to be considered are capable of a double use,—they may be pure modifiers of nouns, or they may stand for nouns. In the first use they are adjectives; in the second they retain an adjective meaning, but have lost their adjective use. Primarily they are adjectives, but in this function, or use, they are properly classed as adjective pronouns."

An English Grammar, 1896, by W. M. Baskervill & J. W. Sewell.

By the way, what does it mean "make head or tail", Molly? Is it an idiom?

Neither head nor tail, neither beginning nor end; neither
this thing nor that; nothing distinct or definite; -- a
phrase used in speaking of what is indefinite or confused;
as, they made neither head nor tail of the matter.
[Colloq.]
