解説 Definition
シカゴ都市圏の通勤電車システムの名称。メトロポリタン・レール・トランジット（Metropolitan Rail Transit）の略称で、広域な公共交通を提供する。
Metra is the commuter rail system serving Chicago and numerous surrounding suburbs in northeastern Illinois. The proper name refers to the regional network and its services, trains, stations, schedules, and operating organization, rather than to urban rail systems in general.
覚え方のコツ Memory Tip
交通機関名なので通常は Metra と大文字で書く。metro に似た音から都市鉄道を連想しつつ、「Chicago」「commuter rail」「from the suburbs」の三点で固定する。市中心部だけの地下鉄ではなく、郊外とシカゴ中心部を結ぶ通勤鉄道網である。「take Metra to work」「Metra schedule」のような固有名詞の用例をまとまりで覚える。
Capitalize Metra because it is the brand name of the Chicago region’s commuter rail system. Its similarity to metro can remind you of metropolitan transportation, but keep the systems distinct: Metra mainly links Chicago with its suburbs, while Chicago’s “L” provides urban rapid transit. Anchor the word in common expressions such as “take Metra to work,” “a Metra train,” and “the Metra schedule.” A mental picture of commuters traveling from an Illinois suburb into downtown Chicago makes the intended proper-name sense clear and prevents confusion with unrelated Greek or medical forms spelled metra.
例文

metra の語源・成り立ち Etymology
ギリシャ語「metra（μήτρα）」＝「子宮」に由来し、語根は「mētēr（母）」と同源。医学用語で子宮を指す接頭辞 metr- の基となり、metritis（子宮炎）やendometrium（子宮内膜）などの関連語を生んだ。「母なるもの」という原義が臓器名に転じた語。
Metra was adopted as the public name of Chicago’s commuter rail organization in the 1980s. The coined brand evokes metropolitan rail and transportation, making its function readily recognizable, but it should be treated as a proper name rather than expanded as a standard English abbreviation. In this transport sense, it is unrelated to Greek mḗtrā, “womb,” found behind certain medical combining forms. Modern usage applies Metra to the Chicago-area commuter network and organization.
