覚え方のコツ Memory Tip
boil「沸かす・沸騰する」に、装置を表す -er が付いて boiler「水を沸かす装置」。boil の末尾 e を落として -er を付ける綴りに注意する。家庭なら the boiler keeps the house warm、工場なら steam boiler のように、湯・蒸気・暖房と結び付けて覚える。
Break boiler into boil plus -er: it is equipment that boils or strongly heats water. In spelling, the final e of boil is not repeated; the result is boiler. Picture the unit in a basement supplying hot water or sending heat through a building. In industry, a boiler may produce steam for machinery or other processes. Useful combinations include central-heating boiler, steam boiler, boiler room, and check or repair the boiler. This word names the heating equipment itself, whereas a kettle is a smaller household container used mainly for boiling water.

boiler の語源・成り立ち Etymology
古フランス語 boillir（沸騰する）を経てラテン語 bullīre（泡立つ）に由来し、語根 bulla は「泡」の意。-er は動作主・道具を示す接尾辞。関連語に ebullient（沸き立つような）や bulletin（掲示＝元は教皇の印章の泡状封蝋から）がある。液体を沸かす装置という意味が直感的に理解できる。
Boiler is built from the verb boil and the instrument-forming suffix -er, literally denoting something used for boiling. Boil entered English through Old French boillir and ultimately comes from Latin bullire, “to bubble or boil,” derived from bulla, “bubble.” The noun boiler became established for vessels and machinery that heat water or generate steam. The same underlying image of bubbling appears in ebullient, whose figurative sense describes someone overflowing with lively enthusiasm.
