Learned this already, but the third person form is new. Not too bad at all

Sources:

JSL Textbook


First Person / As a Question

Verb - Take pre-ます form / form, add the adjectival たい.

Noun - Use the adjectival 欲しい. (Takes particle for object).

Ex.

このケーキを食べたいです - “I want to eat this cake”

新しい枕がほしいです - “I want a new pillow”


Third Person

You don’t know what is in another person’s heart, so you use がる (“to show signs of thinking”).

Verb - Take pre-ます form / form, add the connect to verbal たがっています.

Noun - Use the verbal 欲しがっています. (Takes particle for object).

Ex.

彼はこのケーキを食べたがっています - “He wants to eat this cake”

彼女は新しい枕を欲しがっている - “She wants a new pillow”


Want Something to be Done for You

Structure: -form verbal + 欲しい adjectival / もらい + たい adjectival / いただき + たい adjectival.

いただきたい is the humble version.

Same rules as above for third person. Use for the person who is performing the action for you.

Ex.

ジムさんにスーパーで人参を買ってほしいです - “I want Jim to buy carrots at the super market (for me)”

あなたは私に本を読んでもらいたいですか - “Do you want me to read a book (for you / to you)”

ジム先生にいらっしゃっていただきたい - “I want Jim Sensei to come (for me)”


Invitations

You don’t use the want/desire form to invite people to do things in Japanese. Instead, you use negative questions.
