What does fuselage mean?
Fuselage is a noun referring to the main body of an aircraft: the elongated central structure that houses the cockpit, cabin, passengers, and cargo, and to which the wings, tail assembly, and sometimes engines are fixed. It is the standard technical term in aviation, used by pilots, engineers, regulators, and aviation journalists alike; the plural is 'fuselages'. The word entered English from French in the early twentieth century, derived from 'fuseler' (to shape like a spindle), itself rooted in 'fuseau', meaning spindle — a nod to the slender, tapered profile idealised in early aircraft design. In modern usage it extends naturally to spacecraft and missiles, whose bodies are also called fuselages. Because airframes are subject to intense stress over their service lives, the word frequently appears in safety and maintenance contexts, such as inspections for fatigue cracks or damage to the fuselage skin. Precise and evocative, it is essential vocabulary for anyone reading about aviation.
nounThe main body of an aircraft, to which the wings, tail, and engines are attached and in which crew, passengers, and cargo are housed.
- The central body of an aircraft, housing crew, passengers, and cargo, to which wings and empennage are attached.
"The aircraft's fuselage was dented by a hailstorm at cruising altitude."
"Passengers were evacuated through the doors along the fuselage after the emergency landing."
"Engineers inspected the composite fuselage for hairline cracks following the hard touchdown."
A regular countable noun; the plural is used when discussing multiple aircraft types or production runs, though in everyday speech about a single plane the singular predominates.
"Both prototypes featured aluminium fuselages."
'Fuselage' comes from the French word for spindle — because early engineers thought an aeroplane's body should be as slim and tapered as one.

Etymology of fuselage
Fuselage was borrowed from French around the dawn of powered flight in the early twentieth century, ultimately deriving from 'fuseler', to give something the shape of a spindle, based on 'fuseau' meaning spindle. The underlying image — a long, slim, tapering form — reflects the streamlined body early designers sought for aircraft. The same root gives English words such as 'fusiform' (spindle-shaped) and relates to 'fusee'; the connection lies in shape rather than function, since none of these terms concern aviation directly except fuselage itself.
How fuselage is actually used
A technical term used chiefly in aviation and aerospace contexts; it is neutral in register but rarely appears in everyday conversation outside discussions of aircraft. It is a countable noun with a regular plural ('fuselages').
Easily confused with fuselage
A fusil is a type of light flintlock musket, whereas fuselage is the main body of an aircraft — both derive from French 'fuseau' (spindle) but denote entirely different things.
