Grammar reviewWill vs. Going To — key differences in American English
Both will and going to express the future, but they are used in different situations.
Use will for:
• Spontaneous decisions made at the moment of speaking: "The phone is ringing. I'll get it."
• Predictions based on opinion or belief (no clear evidence): "I think it will rain tomorrow."
• Offers, promises, and requests: "I'll help you move this weekend."
Use going to for:
• Plans and intentions already decided before speaking: "We're going to visit my parents next month."
• Predictions based on current evidence or what you can see/know: "Look at those clouds — it's going to rain."
Note on American English:
In everyday American speech, going to is very commonly contracted to gonna in informal contexts, but in writing and formal speech, going to is standard. Both will and going to are widely used — American English does not show a strong preference for one over the other the way some other varieties do.
