I am active in a small Latin Discord group; a member brought up a question concerning the validity of the following phrase with chained enclitics:
Valēsneque?
(with the enclitics distinguished) Valēs-ne-que?
I assume that their intent was to convey something that fell around the following sentiments; it was not difficult for me to clearly interpret what he was trying to say:
And how are you?
And are you [doing] well?
etc.
However, I asserted that it was not valid, and offered a potentially suitable alternative like "et ut valēs?"; another member offered the equally suitable "atque ut valēs?".
I assumed that valēsneque was invalid largely based on two reasons: one, the fact that, other than words with unremovable enclitics that have taken on a separate meaning (see: quīcumque, quaecumque, quodcumque and others like it), I have never encountered any instance of chained enclitics anywhere; and secondly, the fact that Latin is classified as a fusional language, and that if valēsneque was indeed valid, it would be a potentially interesting case of agglutination in a fusional language.
This leads me to my primary question: is the chaining of enclitics -que, -ve, -ne in sequences like valēsneque valid or not?
