Actually — “angel” could be ‘cherub’ → remove ‘C’ (credits) → ‘herub’? No. “Angel” = ‘spirit’ → remove ‘C’ → ‘spirit’? No C.

A cleaner solve: Take → maybe “SERAPH” (angel) → remove ‘C’ (credits) → SERAPH – C = SERAPH? Doesn’t work.

I suspect this is a joke clue for (as in ‘angel’ lacks credits = no money = ‘A’ grade in sexual act? = ‘A’ as in top mark? Or simply ‘limp’? Final verdict: It’s not a standard cryptic without a setter’s answer key. As a literary fragment, it works best as a surreal, melancholic one-liner about divine or emotional exhaustion in intimacy.
