I know that in regards to writing, there are tons of cognates but that’s only in text (such as: hôtel / hotel, table, garage & etc). Instead, can speakers of either language understand each other when having a verbal face to face conversation? Both languages are from different backgrounds: French is part of the Romance group while English is a Germanic one.
I heard the word “orderves” maybe 100 times, and read the word Hors d’Oeuvres also like a hundred times before I realized they were the same word. So no.
