>R&D is their forté

not correcting you, just edifying everybody on the history of forte's place(s) in the English language

in English, there is no word forté because such a word does not exist in French (and English and Italian don't use diacritic accents)

forte pronounced "fort" is the french word for "strength" (feminine form if memory serves)

forte pronounced "fortay" is the italian word for "loud"

the word most people mean most of the time is the French one because that word entered into English back when most latinate words did, with the Norman invasion in 1066. (French didn't use diacritics then either)

only in the music context do we use the Italian word.

Interesting! Grew up attending chorus for years and years, so the music form is the only one I’ve ever seen :)
