～は～が (topic has attribute)

• 読み: は〜が
• ローマ字: wa ~ ga
• 形: Topic は + Subject が + Predicate (state/attribute)

意味

A construction that relates a non-controllable state, attribute, or ability to a topic. The は marks the overall topic, while が marks the specific subject of the attribute or state being described.

The は～が construction is used to describe inherent attributes, abilities, preferences, or non-controllable states about a topic. The topic marked by は provides context, and the が-marked element specifies what aspect is being described. For example, 象は鼻が長い (as for elephants, their noses are long) describes an inherent physical attribute. This double-subject construction is characteristic of Japanese and has no direct English equivalent. Common patterns include: describing body parts (田中さんは目が大きい), abilities (彼女は英語が上手だ), preferences (私は猫が好きだ), desires (水が飲みたい), and needs (お金が要る). The は and が serve distinct grammatical roles and cannot be interchanged in this structure.

正しい言い方

• 兄はスポーツが得意だ。
• この町は空気がきれいです。
• 祖母は耳が遠くなった。
• 日本は電車が便利です。

避ける言い方

• 日本が春が美しい。(The overall topic needs は, not が — using double が creates confusion about which is the topic and which is the subject) → 日本は春が美しい。
• 田中さんは料理は上手です。(The specific attribute being described takes が, not は — using は would create an unwanted contrastive reading) → 田中さんは料理が上手です。

起源と歴史

This double-subject construction reflects the Japanese topic-comment structure. は establishes the topic frame, and が introduces the specific subject within that frame whose state is being described. It has been a fundamental pattern since classical Japanese.
