Both と (to) and や ( ya ) connect nouns the way ” and ” in English does. Using と is for a list of all items, while や is for a sample of representative items. ” There are noun1 ‘ ya ‘ noun2 ” means “there are noun1, noun2, and other things.”
③テーブルの上にりんごやみかんなどがあります。
Sometimes you can add など ( nado ) after the last noun. など ( nado ) means etc., so you can emphasize that there are more items.
The Japanese language is not so strict about pluralization as English is.
Normally the word ねこ which means cat , can be a cat, some cats or cats in general. There are some specific words and suffixes to pluralize nouns, but when you are a beginner please don’t worry too much about whether they are singular or plural.
ねこが好きです。 I like cats ( in general )
あそこにねこがいます。can be “there is a cat over there” or “there are some cats over there”.
友だちと学校へ行きます。 can be ” I go to school with my friend ” or ” I go to school with my friends.”
つゆ is the word for rainy season in Japan. We have another word for the rainy season. It is うき which means “rainy period” . Japanese うき is つゆ so we use つゆ when we talk about Japanese rainy season.
“Yo” indicates mild emphasis when the speaker is very sure of what she or he is saying.
このクッキーとてもおいしいですよ。
This cookie is delicious. ( so I recommend this cookie. )
It is often used to convey informarion which the listener doesn’t know.
パーティは何時からですか。→ 3時からですよ。
What time does the party start? → It starts at 3:00.
You can use “yo” to get someone’s attention.
晩ごはんですよ! Dinner’s ready!!
“Yo” can also be used when the speaker is making a judgment, so be careful not to put too much stress on it, and do not overuse it; otherwise you might sound aggressive.
