Surface Forms

Morphology

united + state + department + of + Defense

The name is compositionally built from familiar parts: 'United States' (the nation) + 'Department' (an organizational unit) + 'of Defense' (responsible for defence/military matters), so a learner who knows those words can infer it is the U.S. government body that handles national defence. This government-organization naming pattern is cross-linguistically common, making the meaning directly derivable and immediately understandable to B1 learners.

Etymology

United States Department of Defense came when the U.S. joined its main military services after World War II so they could work together. The words show its job: United means brought together, States refers to the country, Department is a government office, and Defense means 'to protect the country', so the name means the government office that protects the nation.
