Clear up vs. Clear out – Which is Correct?

Both “clear up” and “clear out” are correct phrasal verbs, but they express different actions. “Clear up” means clarify confusion, solve a problem, tidy a place, or improve weather. “Clear out” means remove everything from a space or leave it, often quickly. Choose based on whether you clarify or evacuate.

Clear up or Clear out – Which is Correct?

Clear up and clear out are both correct expressions in American English. The difference is the particle: up often suggests completion, improvement, or clarification, while out suggests removal, departure, or emptying.

Use clear up when you want to resolve a misunderstanding, explain something, tidy a mess, or describe improving weather. Use clear out when someone removes items from a place or leaves an area, sometimes abruptly.

The Best Trick to Remember the Difference

Remember the direction suggested by each word: clear up = make something better or clearer, while clear out = make something empty or leave. If the sentence involves an explanation, confusion, mess, or clouds, choose clear up. If it involves objects, a room, or people leaving, choose clear out.

How to Use Clear Up

Clear up has several related meanings. It can mean to explain or resolve confusion, settle a disagreement, tidy a place, or improve weather. It can also describe an illness or skin condition becoming less severe. The expression is common in both casual and formal English, although more formal writing may use alternatives such as clarify, resolve, or eliminate.

When it means “clarify,” clear up may be used with an object: clear up a misunderstanding or clear up the confusion. It can also appear without an object when the meaning is understood from context: The issue should clear up soon.

Example 3: The clouds should clear up by late afternoon.

Etymology of the Phrase Clear Up

Clear comes from an Anglo-French and Latin word associated with brightness, openness, and being easy to understand. The adverb up comes from Old English and conveys a higher, completed, or improved state. Together, clear up developed meanings involving making something bright, orderly, understandable, or resolved.

How to Use Clear Out

Clear out generally means to remove people or things from a place. When used with an object, it often means emptying a room, container, building, or storage area: clear out the closet. When used without a direct object, it can mean leaving, often quickly or because someone has been told to go.

The expression is especially common in informal conversation. In the imperative form, Clear out! can sound forceful, rude, or threatening. In professional contexts, use more neutral alternatives such as leave the area, vacate the premises, or remove the contents.

Example 1: We are going to clear out the basement before the renovation begins.

Example 2: The store is clearing out its old inventory at discounted prices.

Example 3: The security guard told the crowd to clear out of the entrance.

Etymology of the Phrase Clear Out

Clear developed from words connected with brightness, openness, and freedom from obstruction. Out comes from Old English and indicates movement away from an enclosed or central place. The combination clear out came to describe removing obstacles, emptying a space, or departing from an area.
