Surface Forms

in the know positive

Morphology

in + the + know

The meaning 'having insider information' is directly inferable from combining 'in' (inside) with 'know' (knowledge) — essentially being 'inside knowledge'. The determiner 'the' does not obscure the sense, and the concept of being 'in' a state of knowledge is cross-linguistically common, so a B1 learner who knows the constituents will likely understand this phrase.

Etymology

The phrase in the know paints a simple picture: someone who is in a small group that know the important facts. So it means 'having special information'.
