Etymology

Origin of artillery

1350–1400; Middle English artil ( le ) rie, artelry, art ( u ) ry armaments, ballistic engines < Anglo-French, Middle French artillerie, equivalent to Old French artill ( ier ) to equip, arm, alteration, by association with art art ¹, of atill ( i ) er to set in order, put on armor (< Vulgar Latin *apticulāre, derivative of Latin aptāre to put on (armor, ornaments, etc.; adapt ); -i- for expected -ei- perhaps by association with atirier; attire ) + -erie -ery

Explanation

Artillery refers to large-caliber guns — guns with big barrels — which can be moved from one place to another for land battles. The artillery is also the name for the army unit that uses these big guns. If you're a military commander and you say, "Bring in the heavy artillery," you're ordering the artillery to move into place and get ready for action. But if you're talking to fellow members of your debate team and you say, “Bring in the heavy artillery,” you mean "bring in our best debaters, our heaviest hitters." Artillery can refer to one weapon or 100 — the singular and plural are the same.
