नौसेना (nausenaa)

noun A compound noun meaning 'navy' -- built from नौ (nau, 'boat/ship') and सेना (senaa, 'army/force'). One straightforward sense.
Sense 1 : navy
noun, feminine
Synonyms: जल सेना (jal senaa, less common two-word variant)
Frequency: medium
Cultural Note: नौसेना (nausenaa) sits alongside थलसेना (thalsenaa, 'army', literally 'land force') and वायुसेना (vaayusenaa, 'air force') as the three branches of the armed forces -- you'll see all three named together in news broadcasts and Republic Day coverage. The सेना (senaa) root is the same one used for 'army' generally, so recognizing that piece unlocks several related compound words at once.
Common Mistakes: 1) Learners sometimes try to pluralize it like an English collective noun ('the navies'); as a mass/institutional noun in Hindi it usually stays singular even when referring to naval forces collectively, similar to सेना (senaa, 'army') and वायुसेना (vaayusenaa, 'air force').
