alternating patterns

[Anton]

I have a vague impression that somehow we can kinda sort that out.

See, for Latin "et any et any" is higher than expected. Since it's opposite to what we see in Dante and the Bible, I suspect this is due to stilistics of Latin, where instead of a simple list (such as would be comprised with commas nowadays), the elements of a list are consistently interleaved with "et". Like instead of "dogs, cats, birds, fish and lions" you'd say "dogs and cats and birds and fish and lions".

I'll bet that "et et", though, would turn out to be lower than expected, since it's basically an invalid biword (sorry David!) in Latin.
