① たべます » たべたい
-- To eat » want to eat
② I want to go to Japanese restaurant to eat sushi.
-- わたしは日本料理のレストランへ寿司を食べに行きたいです。
③ です = であります
-- Just in case if you're taking JLPT.
④ There are 3 groups of verbs so they are to be changed differently in different situations.
Group 1 mainly consists of verbs that end with consonant. For example: かき kaki
So, its plain/casual form will be: かく
So the last hiragana, き will be changed to the う line and become く.
Group 2 mainly consists of verbs that end with a vowel. But not all verbs that end with the "i" are in this group. Sensei said that we can only memorise where which one goes.. T_T
For example: たべ tabe
So, its plain/casual form will be: たべる
Just add a る will do.
Group 3 consists of irregular verbs and they are きます and します。
きます » くる
します » する
Just move them to the う line and add る, so you can say Group 3 is a combination of Group 1 and Group 2. XD
For verbs that come from nouns, they are in this group as well, like: べんきょうします
べんきょうします » べんきょうする
おやすみなさい~!
