What “Bare” means
In Jamaican Patois, bare before a noun means "only" or "nothing but": "bare rice" is rice and nothing else. It often hints that something is missing or that there's too much of one thing.
Examples
Bare rice deh inna di pot.
There's only rice in the pot.
How to use it
Casual, everyday speech.
Where usage varies
In London and other UK slang, "bare" usually means "a lot" or "very" ("bare people"), which is a different sense. Speakers in the diaspora may use both, so check the context.
