酔っ払う

1. Origins, structure, and basic meaning

• Structure: 酔っ払う is read as よっぱらう and is a colloquial godan intransitive verb meaning to become drunk from alcohol.
• Basic usage: Use すぐ酔っ払う for getting drunk quickly and 酔っ払う前に for an action taken before that state.

2. Common pitfalls and similar expressions

• Register beside 酔う
  • It is more conversational and can make the drunken state more vivid than neutral 酔う, so register matters.
• Clue to the amount
  • 少し飲んだだけで says that only a small amount was enough; it should not be expanded into heavy drinking.
