Definition

1. Verb (transitive):
   • To expose something to the air, especially cool or fresh air, in order to ventilate, freshen, dry, or cool it. This involves allowing air to circulate through an object or space to remove odors, dampness, or stale air.
   • To express one's thoughts or feelings openly; to discuss something openly. This meaning is less common and is often used in the context of discussing problems or grievances.

Usage and Examples

• Primary Meaning (Ventilate/Freshen):

Advanced Usage and Notes

• The phrasal verb is separable. The object can come between "air" and "out" or after it.
  • Please air the room out. (Object between)
  • Please air out the room. (Object after)
• Often used for items that have been stored (clothes, bedding) or spaces that need refreshing (rooms, cars).
• The "discuss openly" meaning is more informal and figurative, extending from the idea of letting fresh air (or ideas) circulate.
