Meaning
Even up to now; still — used to stress that something long expected has still not happened after a wearing wait. 'All now him nuh come' means he still hasn't come, even after all this time, with a note of impatience or resignation. It marks the stretch of time gone by against a thing that ought to have occurred and hasn't, and it is a common everyday way of complaining that a person is late, a promise unkept, or an outcome overdue.
