Is this a correct translation? “This pizza is good!” →　このピザは　いいです。 [Answer] It is not appropriate. The adjective “good” has many meanings. You can use sentences like this; それは　いいアイディアですね！　That is a good idea. いい　りょこうでした。 It was a good trip. レストランのサービスは　よかったです。The customer service at the restaurant was good. In some cases, however, いい is not an appropriate translation. Let’s look at these four major usages referred to the English-Japanese dictionary “ジーニアス” the 3rd edition. 1. good health →　げんき（な） 　As greetings, you may hear that げんきですか？― はい、げんきです, these means “how are you? – I’m good.”. 2. skillful →　じょうず（な） 　My friend is good at tennis. →　ともだちは、テニスが　じょうずです。 　When you describe “good skill”, じょうず is used. 3. tastes →　おいしい 　This is how EIGO translation is necessary between English and Japanese. English: good EIGO: delicious Japanese: おいしい If you wish to describe something exactly in Japanese, you can try using synonym depending on the listener’s response/reaction. わたし：　 このピザは　いいですね！ This pizza is good, isn’t it? ともだち：　・・・ わたし：　おいしいですね！ Delicious, isn’t it? ともだち：　はい、おいしいですね！ Yes, it is. (Thank you, my friend.) 4. right, correct, proper →　ただしい and いい In the JLPT question sentence says “１・２・３・４から いちばん いい ものを ひとつ えらんでください”, and this いい means “correct, suitable, appropriate”. わたし：　 このピザは　おいしいですね！This pizza is delicious, isn’t it? ともだち：　・・・ わたし：　わたしの　にほんごは　いいですか？ Is my Japanese good? ともだち：　もちろん、ただしいですよ。すみません、いま、たべていますから、なにも　いいませんでした。 Of course, it’s correct. Sorry, I didn’t say anything because I’m eating right now. That’s all for today! FYI, the “like” button on SNS is いいね in Japanese. But that’s another story. Thank you for reading☆
