diáfano (Adjective) (especially of fabric) "translucent," "transparent"
Borrowed from Medieval Latin diaphanus "transparent," itself borrowed from Ancient Greek διαφανής (diaphanés) 'id.,' from διά- (dia) "through" and φαίνειν (phaínein) "to shine" (see fantasma for a continued etymology). Ancient Greek διά-, more literally read as "in two," probably derives from a pre-form *diha-, and thus is from Proto-Indo-European *di̯s "apart" (see dis-).
