What does fusilier mean?
A fusilier is, at heart, a soldier associated with the fusil, a light flintlock musket of the seventeenth century. Regiments raised or re-equipped to carry this weapon were designated fusiliers, and the title endured long after the weapon itself became obsolete. Today the word chiefly denotes a member of a fusilier regiment — such as the Royal Regiment of Fusiliers in the British Army — where it signals membership in units noted for their distinctive uniforms, ceremonial bearskins, and long martial traditions. A second, unrelated sense belongs to the sea: 'fusilier' is also the common name for slender, brightly coloured schooling fish of tropical reefs, prized by divers for their shimmering bands of blue and yellow. Whether on the parade ground or the coral shelf, the word carries an air of precision and heritage, linking a military term born of early firearms technology to one of nature's most vivid displays of colour.
A soldier armed with a fusil; now, a member of a fusilier regiment in the British or other Commonwealth armies.
"The young fusilier stood proudly in his regiment's ceremonial dress."
Historically distinguished from grenadiers and regular infantry by their weapon and role guarding artillery.
Any of various slender, brightly coloured tropical reef fish of the family Caesionidae, commonly called fusiliers.
"Divers watched thousands of fusiliers swirling above the reef in silver-blue schools."
Standard plural; used for both the military sense and the fish.
"The fusiliers marched in step behind the regimental band."
The name comes not from the gun but from the spark: 'fusil' originally meant the steel used to strike fire for a light — the very thing these soldiers once kept burning at their matchlocks.

Etymology of fusilier
Fusilier comes from the French 'fusil', meaning a light musket, which itself traces back through Old French to a Vulgar Latin form derived from 'focus', meaning hearth or fire — the word originally denoting the steel used to strike sparks when lighting a flame. When European armies adopted the lighter flintlock weapon, soldiers armed with it were called 'fusiliers', a designation that spread from France into English usage in the seventeenth century. The French verb 'fusiller', source of 'fusillade', shares the same root, as does the English term 'focus', ultimately from the same Latin word for hearth.
How fusilier is actually used
In modern usage the word almost always refers to a soldier in a fusilier regiment (such as the Royal Regiment of Fusiliers) and carries connotations of regimental tradition and pride. The zoological sense, referring to slender reef-dwelling fish, is largely confined to diving and marine-biology contexts. Plural is simply 'fusiliers'.
