sober up

Definition

phrasal verb. to become less drunk or to make someone else become less drunk. You use this when someone needs to get their clear mind back after drinking alcohol.

phrasal verb. to become or cause to become sober after a period of intoxication. The verb functions both intransitively (the subject recovers) and transitively (an external factor or time causes the object to recover).

Examples

“I need to drink some water and sober up before I go home.”

“After the wild party, he spent two hours walking around the park to sober up before his parents arrived.”

“The cold morning air and a strong cup of black coffee did little to sober up the exhausted revellers after their night of excess.”

Teaching tip

contrast with 'dry out', which refers to a long-term recovery from alcoholism rather than a short-term recovery from a single night of drinking.
