“naval” vs. “navel”
Write "naval" only as an adjective describing ships, navies, or sea-based military matters; write "navel" for the belly button or the navel orange.
naval
"Naval" is an adjective meaning relating to a navy or to ships and naval warfare ("a naval base," "naval history"). It comes from Latin "navalis," an adjective built from "navis" (ship), the same root that gives English "navigate" and "nautical," placing "naval" firmly within a family of words about ships and sea travel.
navel
"Navel" is a noun naming the belly button, the small scar or depression on the abdomen marking where the umbilical cord was once attached, and by extension it names the small depressed spot at the base of certain fruits, especially the "navel orange," named for the small navel-like formation at its blossom end. It comes from Old English "nafela," related to the word "nave" (as in the central hub of a wheel), both descending from a very old Indo-European word for "navel" or "hub" — the same ancient root shows up across many Indo-European languages for this exact body part.
The real distinction
"Naval" and "navel" are homophones or near-homophones with completely different roots: one comes from Latin "navis" (ship), the other from a much older, separate Indo-European word for the belly button, and they only converge because English happened to spell both with the same letters rearranged slightly. Grammar and topic together settle the choice quickly: "naval" is always an adjective describing something related to ships, navies, or naval warfare, and it will always modify a noun ("naval fleet," "naval academy," "naval officer"). "Navel," by contrast, is always a noun naming either the belly button or, in the specific compound "navel orange," the fruit variety named for its navel-like formation. If the word is describing military ships or sea power, you want "naval"; if the word is naming a body part or that specific citrus fruit, you want "navel." Because "naval" appears constantly in military history and current-events writing about fleets and defense, while "navel" appears in anatomy, yoga and wellness writing (the navel is a common reference point in that context), and produce descriptions, the surrounding topic usually makes the intended spelling obvious well before any grammar check is needed. Beyond the navel orange, several other citrus varieties are named for physical features in a similar descriptive way, though none as widely recognized in everyday grocery-store vocabulary as the navel orange, whose name has become so familiar that many people no longer consciously connect it to the body part at all. Historically, naval power was a central measure of a nation's global influence, and naval history as a field of study covers everything from ancient Mediterranean galley warfare to modern nuclear submarines, an entire specialized field of writing that never once needs the anatomically or botanically focused word 'navel.'

Memory trick
Link "naval" to "navy" — both start identically and both concern ships and sea power. Link "navel" to "belly button" directly, and remember the fruit connection: a navel orange has its own small navel-shaped mark, an easy visual bridge between the anatomical and the citrus sense of the same word.
