"Would like" is a polite way to say "I want" in English.
"I want to buy a ticket" is impolite because "I want" sounds selfish and arrogant.
"I would like to buy a ticket please" is polite and friendly.
Grammar rules for would like
"I would like" is followed by an infinitive verb or a noun.
"I would like to book a double room for Saturday." (infinitive verb "to book".)
"I would like a single room for Saturday." (noun "a single room".)
Because "would" is a modal verb, it doesn't change for he / she "third-person singular".
I would like
You would like
He / she would like
We would like
They would like
There is no "s" on he / she / it.
You can abbreviate the "would" to 'd:
Don't abbreviate from "would" to "'d" in the question or negative forms.
"I wouldn't like" (not "I'dn't like".)
To form the negative, add "not" or the abbreviation "n't" to "would":
I would not like / I wouldn't like
You would not like / You wouldn't like
He / she would not like / He wouldn't like
We would not like / We wouldn't like

To form the question, change the subject-verb word order to verb-subject:

Would he / she like ...?

The short reply is
Yes, I / you / he / she / we /they would.
