"She always going on ..."

[Odessa Dawn]

always = very often As well as all the time or on every occasion, always can also mean very often when it is used with the progressive form:
She always going on about the cost of living and how expensive everything is.
I'm always losing my keys. I put them down and can never remember where I've put them.

PROGRESSIVE TENSES

Is "She always going on about the cost of living" syntactically acceptable without verb to be (is)?
​

Thank you,

Unless that was reported speech, it's an error and should be "She's ..." or "She is ..."

If reported speech it would probably be Jamaican dialect.
