How to use "pass out"

What Does "pass out" Mean?

The expression pass out is a versatile phrasal verb with two distinct primary meanings. Most commonly, it is used intransitively to mean losing consciousness or fainting, often due to illness, exhaustion, or intoxication. In a transitive context, it means to distribute something to a group of people.

• Meaning 1 (Intransitive): To become unconscious (faint).
• Meaning 2 (Transitive): To hand out or distribute items.
• Compositionality: Semi-idiomatic. While "out" suggests a distribution away from a center, the "fainting" definition is a figurative extension.
• Register: Neutral to informal. In medical contexts, "faint" or "lose consciousness" is preferred, while "distribute" is the formal alternative for the second meaning.

How to Use It

• Grammatical pattern:
  • For fainting: Subject + pass out (Intransitive). It cannot take a direct object in this sense.
  • For distributing: Subject + pass out + Object OR Subject + pass [Object] + out (Transitive and separable).
• Typical complements: People often pass out "from" heat, exhaustion, or pain. When distributing, people pass out "leaflets," "flyers," or "exams."
• Separability: When used to mean distribute, you can place the object between the verb and the particle (e.g., "Pass the papers out"). However, when it means to faint, the words must stay together.
• What sounds unnatural: Using "pass out" to mean dying (which is "pass away") or using it transitively when you mean fainting (e.g., "The heat passed me out" is incorrect; use "The heat made me pass out").

FAQs

Can the parts of the phrasal verb be separated by other words

However, when it means to lose consciousness, it is intransitive and the parts cannot be separated. You can "pass the tests out," but you simply "pass out" if you feel dizzy.
