Enharmonic

(in modern musical notation and tuning) note, interval, or key signature that is equivalent to some other note, interval, or key signature but "spelled", or named differently

In music, two notes, intervals, or key signatures are enharmonic if they sound the same but are written in different ways. For example, C-sharp and D-flat are enharmonic notes. C-sharp major and D-flat major start on enharmonic notes, so they are enharmonic key signatures, but they have different numbers of sharps and flats. An augmented fourth and a diminished fifth are enharmonic intervals, because they both cover 6 half steps.[1]
