The correct choice depends on what you are trying to say, but the most common and natural option is “about.”
Here are the two ways you can complete that sentence, depending on your intent:
1. The Most Common Way: “About”
“I’m thinking about going to the gym.”
Use this when you are considering the idea. You haven’t fully decided yet, or you are simply mentioning what is currently on your mind. In English, we almost always use “thinking about” followed by a verb ending in -ing.
2. The Direct Plan: “Of”
“I’m thinking of going to the gym.”
This is also grammatically correct and means essentially the same thing as “about.” It often implies you are weighing the option or have a slight intention to go.
- الاجابة : about
Which one should you use?
Use “about” for 90% of situations. It sounds the most natural in casual conversation.
Avoid using “to” in this specific structure (e.g., “I’m thinking to go” is generally considered incorrect in standard English; you would instead say “I plan to go”).
