Morphology

forlorn + hope

The literal meanings of 'forlorn' (hopeless/unlikely) and 'hope' (expectation) would lead a B1 learner to infer something unlikely or desperate, so part of the sense is recoverable. However, the idiomatic use refers specifically to a risky venture or undertaking (a semantic shift from 'feeling' to 'enterprise') and has an archaic/military history, so the full meaning is not fully predictable from the constituents alone.

Etymology

The phrase forlorn hope comes from old wars where small groups of soldiers were sent to lead the most dangerous attacks and often did not return. Because these missions were forlorn, meaning 'nearly hopeless', forlorn hope now means 'a desperate task' with little chance of success.
