Key Difference

• “During” is used with a noun to indicate when something happens.
• “While” is used with a verb phrase (subject + verb) to show two actions happening at the same time.

1. “During” + Noun

“During” is followed by a noun, and it describes a period of time when something occurs.

• Usage: Use “during” to talk about a specific time period or event.
• Examples:
  • “I took notes during the meeting.” (The meeting is a noun, and the action happens within this period.)
  • “He fell asleep during the movie.” (The movie is a noun representing the time period when he fell asleep.)

Think of “during” as highlighting a block of time when something else takes place.

2. “While” + Subject + Verb

“While” introduces a clause (a subject and a verb), and it connects two actions that happen at the same time.

• Usage: Use “while” with a clause to describe two simultaneous actions.
• Examples:
  • “She listened to music while she was studying.” (Both listening and studying happened at the same time.)
  • “I cooked dinner while he set the table.” (Both actions were happening at once.)

📝 Notice the Structure

When using “while,” you need a subject (like “she” or “I”) and a verb (like “was studying” or “cooked”). This is a full sentence part or clause, not just a noun like with “during.”
