Translation guide
Expressing eagerness in Japanese depends on whether you are describing a strong personal desire, a keen interest, or an enthusiastic willingness to do something. Common patterns include 〜たい, 〜たがっている, 〜たくてたまらない, and 乗り気.
I'm eager to go.
He is eager to help.
Expressing a strong personal desire to do something.
Attach to the masu-stem of a verb to express 'I want to do X'. This is the most direct way to express eagerness for an action.

Expresses an unbearable desire to do something. Stronger than 〜たい alone.

Talking about a third person's desire or eagerness.
Used to describe someone else's apparent desire to do something. Based on 〜たい but for third person.
In Japanese, you cannot directly say 'He wants to do X' using 〜たい because it expresses internal feelings. Use 〜たがっている or add そうだ (e.g., 〜たそうだ) to report what you've heard.
