G♯11 — G♯, B♯, D♯, F♯, A♯, C♯ — is a dominant 11th chord: stacked thirds up through the 11th over a dominant 7. The third is almost always omitted in practice because the 11th sits a half-step above it — the classic suspended colour.

Common mistakes
The defining note is the 11th (C♯). It sits more than an octave above the root, which is why the chord needs a wide voicing — in tight piano voicings the 11th usually appears in the top register while the root and lower triad tones cluster below.
In context
Functions as a V-sus colour — the 11th replaces the 3rd, giving the chord a suspended, unresolved feel before final resolution.
