The だ form is the plain/casual form of the copula (です / desu), meaning "is." ### Grammar Tip: In Japanese, the topic particle は (wa) is used to indicate the subject or topic of the sentence. It is often followed by a description or statement about that topic. In this sentence, 空気は (kūki wa) and 街は (machi wa) are the topics, and the adjectives 煙く (kemukū) and 賑やかだ (nigiyaka da) describe them. When using い-adjectives (e.g., 煙い / kemui), the く form (煙く / kemukū) is used to describe how something is (e.g., "the air is smoky"). For な-adjectives (e.g., 賑やか / nigiyaka), the copula だ (da) or です (desu) is added to complete the sentence (e.g., "the town is lively"). ### Related Words: - 煙 (けむり / kemuri): "Smoke" (noun). - 賑わう (にぎわう / nigiwau): "To be bustling" or "to be crowded" (verb). - 静かだ (しずかだ / shizuka da): "Quiet" (な-adjective, opposite of 賑やかだ). - 澄む (すむ / sumu): "To be clear" (verb, often used for air or water, opposite of 煙い). This sentence contrasts the smoky air with the lively town, creating a vivid image of the environment. |
