The Cm/G chord is a C minor chord, with the G (the 5th) as the bass note.
The C minor chord itself has a dark, melancholy sound. Playing the 5th of the chord (in the case of Cm, the 5th is G) as the bass note, can make the chord sound even more dark and dramatic, even if it is only a subtle difference.
The chord is also referred to as C minor over G, or Cm ‘slash’ G, or simply, C minor with an G in the bass.
Technically, the C minor chord with the G in the bass is a second inversion C minor chord.
