Enharmonic
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]

Comparison of intervals near or enharmonic with the unison
The notes F♯ and G♭ are enharmonic equivalents.
E♯ and F♭, however, are not enharmonic equivalents, because E♯ is enharmonic with F♮.
G
and B
are enharmonic equivalents, both the same as A♮.
