Morphology

on + the + lam

Assuming the learner knows the verb 'lam' (to run off to evade arrest), the phrase is compositionally predictable: 'on' marks a state/location and 'the lam' functions like other nominalized run-states (cf. 'on the run'), so the overall meaning 'in hiding/on the run' follows directly. Although 'lam' is informal/slang, the syntactic pattern is transparent and readily interpretable by learners who know the constituents.

Etymology

On the lam comes from old criminals' slang. Lam was a short word meaning 'to run away', and people who were running away from the police were said to be on the lam, so today it means 'in hiding or on the run'.
