French grammar question : 'couvert de' preceding a plural noun

Factual Questions

Hi

I’m interested in why ‘couvert de’ precedes a plural noun. The answer seems to be ‘haplologie’. . Can anyone verify the grammar rule behind ‘covert de’ and the rule posted below.
I look forward to your feedback.

PS : Vérification faite dans le Grévisse, pour “je parle de confiture” on dit que avec la préposition “de”, l’article partitif s’efface par haplologie. (donc de + de la = de comme de + du = de qui donne “il est couvert de sable” “je parle de confiture”

Because the items covering whatever are countable. While French grammar doesn’t talk about “countables” and “uncountables”, the underlying concept is the same.

If the covering was a material then the noun would be singular. If the covering was multiple items, then the noun is plural. Just as in English or Spanish to name two (I suspect, just as in any language with different nouns for singular and plural). “Covered in gold” vs “covered in coins”.

“Haplologie” has nothing to do with singular vs plural. It’s about eliminating redundancies (you don’t say “de de”; if the second “de” would be followed by an article, this article is ellided along with its preposition; this applies to the contraction “du” as well).

I think the point is slightly different. “Couvert de [fleurs]” focusses on the covering by [flowers in general].

If you were to say “des fleurs” I think it might be expected to refer to some specific flowers already mentioned and already the focus of attention.
