~てあげるto do something for someone
Used when the speaker (or someone close to them) performs a favor for someone of equal or lower social status. It focuses on the giver's perspective and intention to help. Be cautious using it directly to a person of higher status, as it can sound slightly patronizing by emphasizing that you are doing them a favor.
Common mistakes
- Using it for a superior (should use 'sashiageru')
- Confusing it with 'te kureru' when the speaker is the receiver
- Incorrect particle usage for the receiver (should be 'ni')
