Japanese likes and dislikes are actually na-adjectives. This is different from what we have learned in English where both "likes" and "dislikes" are verbs .
The Japanese word for "like" is 好き (suki) and the one for "dislike" is 嫌い (kirai).
At this moment, try avoiding using them to express your feelings towards people because suki and kirai can mean "love" and "hate" respectively when you say that to a person.
Only use them towards people when you have a good grasp of the language.
So how do you use Japanese likes and dislikes to express your feelings towards something in a Japanese sentence?
It's best to learn by memorizing the sentence patterns. Take a look at the following patterns...
Subject は Noun が すきです
Subject wa Noun ga suki desu
Meaning: Subject likes Noun.
Subject は Noun が きらいです
Subject wa Noun ga kirai desu
Meaning: Subject dislikes/hates Noun.
Take note that since すき (suki) and きらい (kirai) are adjectives, particle が (ga) is used in the expressions. So using some examples...
Since Japanese likes and dislikes are na-adjectives, you need to add "ではありません" (dewa arimasen) at the end in order to form the negative form, just like...
suki dewa arimasen
Meaning: don't like.
kirai dewa arimasen
Meaning: don't dislike.
It's simple to turn the Japanese like and dislike sentences into questions by adding the particle か (ka) at the end, such as...
You have to answer yes or no in this type of question.
When answering "no" to a yes/no question, always remember to change the particle が (ga) to は (wa). Please don't forget this grammar rule.
If you want to ask questions like "What Noun do you like?" or "What kind of Noun do you like?", use the question word どんな (donna). For example, if you want to ask someone "What dish does he like?" or "What kind of dish does he like?...
Other than questions for Japanese likes and dislikes, if you wish to ask someone for his/her preference, use the i-adjective いい (ii) instead. See the following expression...
Topic はどれが いいですか
Topic wa dore ga ii desu ka
Meaning: Which Topic do you prefer?
Using an example to show the expression...
When there are only 3 or 4 choices, use the question word どれ (dore). When there more than 4 choices use the question word なに (nani).
