Questions & Answers about kyou wa kibun ga ii desu kara, toshokan de nihongo o benkyoushimasu.

Why is there a は after 今日? What does 今日は mean?

は is the topic marker. 今日は means “as for today” or “today (speaking about today).” It frames the rest of the sentence as information about today. Note the particle は is pronounced “wa” here. Without は, 今日 can function as a simple time adverb; with は, it adds a slight contrast or emphasis on “today.”

Why does 気分 take が (気分がいい) and not は?

With descriptive predicates (like adjectives), が marks the thing that has the property. 気分がいい states a neutral fact: “(my) mood/condition is good.” Using 気分はいい is possible but tends to contrast it with something else (e.g., “the mood is good, but…”). So が is the default in plain descriptions.

What’s the difference between 気分, 気持ち, and 調子?

気分: mood/overall feeling (often physical/mental condition). Common with いい/悪い. Example: 今日は気分がいい.
気持ち: feeling/sensation; often about how something feels. Example: このお風呂は気持ちがいい (This bath feels good).
調子: condition/performance of a body part, one’s performance, or a machine. Example: 体の調子がいい (My body’s condition is good).

Why is it いい and not よい? Are they the same?

They’re the same adjective. よい is the original/formal form; いい is the common colloquial form. Conjugations often use よ: よく (adverb/te-form), よかった (past), よくない (negative). So you say いいです but よくない, よかった.
