Grammar Notes & Usage Tips
•Conjugation Basics**: As an i-adjective, 暑い follows a straightforward pattern—drop the い for negations and past forms. For example, "It was hot" becomes 暑かった (あつかった), while "It's not hot" is 暑くない (あつくない).
•Particle Pairings**: When describing how hot it is today, use the particle は (wa) to set the context: 今日は暑いです (きょうはあついです), translating to "Today is hot." This emphasizes today as the topic of your sentence.
•Common Confusion**: Don’t mix up 暑い with 熱い (also あつい), which means "hot" in relation to things you can touch, like coffee or a stove. Remember, 暑い is all about the weather!
•Politeness in Expression**: To make your statement more polite, add です at the end: 暑いです (あついです). This small addition keeps your conversation courteous and appropriate for formal situations.
•い-adjective: Conjugates by changing the い ending
