Some Latin words end in -que (for example quinque, vocative of adjectives ending in -quus and imperatives like relinque), but I have never seen the conjunction -que attached to such words. Are there examples of having a double -que in this sense? Do grammarians or other writers suggest avoiding such combinations?
I am not interested in pronouns where the final -que comes from the conjunction, but in words that coincidentally end in -que. The answers to an earlier question indicate that quinque does not have the conjunction -que in it.
Added detail: I am mostly interested in the case where both 'e's are short, that is, words ending in -quĕquĕ instead of -quēquĕ. The answer by brianpck below gives an example with -quēquĕ.
