Morphology

let + me + tell + you

The phrase is compositionally built from 'let' (allow) + 'me' + 'tell' (recount) + 'you', so its literal force — 'allow me to tell you [something]' — directly signals introducing or emphasizing a statement. Although it functions as a pragmatic/discourse marker in spoken English, the meaning is predictable from the constituents and from common imperative/request patterns, so a B1 learner who knows the words will generally understand it.

Etymology

Let me tell you comes from a simple scene where someone asks let me, meaning 'allow me', and then leans in to tell you a story. That's why today people use it to grab attention or to start an important or surprising point.
