Oh, many thanks, jheem. Taking an educated guess, I would expect that these collocated terms must be diagrammed as one unit and not with modifiers separated.

And these 'irreversible binomials' made me laugh because it is such a wonderful mouthful! This will be a terrifically enjoyable term to drop upon someone in my English department soon, not to mention my own students. It sounds so wonderfully mathematical! But I am honest. After I see a jaw or two drop, I'll definitely credit you and AWAD with this new information!

Irreversibly binomially yours,
WW
