コンパス
覚え方のコツ Memory Tip
compasses は compass の規則的な複数形で、語末が -ss のため -es を加えます。発音は /ˈkʌmpəsɪz/ で、語尾に /ɪz/ の音節が増えます。方位を知る羅針盤なら several compasses、円を描く二脚器具なら a pair of compasses という形を典型表現として覚えましょう。
Treat compasses as the regular plural of compass. Because compass ends in -ss, add -es, and pronounce the ending as an extra /ɪz/ syllable: compass, compasses. For navigation, picture several hikers carrying compasses that point north. For geometry, remember the fixed expression a pair of compasses: the two hinged legs open to measure a radius and draw a circle. American English more often calls this drawing tool a compass, while British English commonly uses compasses. Both senses share the historical connection with measuring, enclosing, or tracing a circular range.

compasses の語源・成り立ち Etymology
古フランス語 compas（円・測定具）から。ラテン語 com-（共に）+ passus（歩み）が語源で、歩幅で距離を測ることが原義。円を描く道具や方位磁針の意味に発展した。関連語：compass（羅針盤）、encompass（包囲する）。
Compasses is the plural form of compass. Compass entered English through Old French compas, a word associated with a circle, circuit, measure, or measuring instrument. It is historically connected with the idea of measuring together by steps, reflected in Latin elements com-, “together,” and passus, “step.” From circular measurement, the noun developed uses for drawing instruments and later for instruments that indicate direction.
