Which term refers to someone who is unable to think or act normally due to excessive alcohol consumption?

The term that refers to someone who is unable to think or act normally due to excessive alcohol consumption is "inebriate." This term specifically describes a state of intoxication where the individual’s faculties are impaired as a result of drinking alcohol.

While "alcoholic" typically refers to someone with a long-term dependency on alcohol, and "drunkard" colloquially suggests someone who frequently drinks excessively, "inebriate" directly captures the condition of being inebriated or under the influence at a given moment.

On the other hand, "teetotaler" describes someone who abstains completely from alcohol, which does not apply to the situation of having impaired faculties due to drinking. Understanding these terms in context helps clarify the specific meaning of "inebriate" as it aligns closely with the effects of intoxication.
