Morphology
The meaning is directly and compositionally derived from 'declare' (to formally announce) + 'war' (armed conflict); a learner who knows both words can infer that it means to make a formal announcement of entering a state of war. This construction is cross-linguistically common and follows standard nomination patterns, so it should be immediately understandable to a B1 learner.
Etymology
The phrase declare war comes from the image of a leader making a public, official announcement that their country will fight another. The verb declare means to announce openly and war means open fighting between countries, so the phrase now means 'to officially announce that a country will fight another'.
