I see again why I seldom reply to Alex.
(a) Neuter plurals in Latin originally ended -a:
(b) This was shortened to -a.
(c) On some words, deictic particles (-i and -c) were added, so that the
neuter plural ended in -ai or -aic, which became ae or -aec. In the
Classical period this included neuter plural quae and haec.
(d) This was later extended to other determiners, including ille, new neuter
plural illae.
(e) A phonetic change takes place: -ae- > -e-.
(f) This gives you the final -e on neuter plurals that you are looking for.
So Miguel is not "seriously mistaken"
