Morphology

lost + cause

The adjective 'lost' clearly signals irrecoverability and 'cause' can denote an effort or campaign, so the overall meaning 'an effort with no hope of success' is largely derivable from the parts. However, B1 learners may primarily know 'cause' as 'reason' rather than 'a movement/endeavor', so the intended sense is not fully guaranteed without prior exposure.

Etymology

The idiom lost cause uses cause to mean a fight, plan, or belief and lost to show it is defeated; picture a flag on the ground after a battle or a court case already lost. That's why it means 'no hope of success'.
