/sɔ̃/
sound; A piece (of music); a (musical) work; an opus.
“Le son de ce piano est agréable.” — The sound of this piano is nice.
Synonyms: musique, morceau
Inherited from Old French son, suen, suon, from Latin sonus (the current form may be remade after or influenced by sonner).
bran
“Ceci est du pain de son.” — This bread is done with bran.
Inherited from Latin secundus (presumably through an earlier Old French form *seon; compare an attested Medieval Latin seonno, seonnum). Cognate with Catalan segó, Old Occitan segon. The meaning derives from the fact that bran results from a second sifting of flour. Doublet of second, a borrowing.
