To+infinitive vs For+ing form

 

Summary Table

Category	Form	Meaning	Example
Personal Purpose	To + Infinitive	Intention / Goal	He stopped to eat lunch.
Object Function	For + -ing	What it's made for	This is a tool for opening cans. This knife is for cutting bread. This brush is for painting walls.
Reaction / Reason	For + -ing	Why you feel/act a certain way	I'm sorry for losing your pen Thanks for helping me

Memory Trick: The "Goal" vs. "Cause" Rule

• Use To + Infinitive for the Goal (something in the future you want to achieve).
• Use For + -ing for the Cause (something in the past or present that triggered your reaction).

Example:

• "I brought chocolate to make you happy." (Goal)
• "Thank you for making me happy." (Cause)

REMEMBER

When expressing emotions or reactions (thanks, apologies, reasons for feelings), we almost always use for + -ing:

Context	Example
Gratitude	Thank you for inviting me.
Apology	I’m sorry for being late.
Praise	She was famous for singing jazz.
Blame	He was arrested for stealing a car.

The Contrast

To see the difference clearly, look at how the meaning shifts:

1. Reason for feeling (For + -ing): "I am happy for winning the race." (The win is the reason for the feeling).
2. Purpose of action (To + Infinitive): "I practiced hard to win the race." (Winning is the goal of the practice).
