At your wits' end

Suggest a Correction

Meaning

So worried, confused, or frustrated that you cannot think what to do next. The possessive changes with the subject: my wits' end, his wits' end, and so on. Regional use: Biblical English; now widespread.

Origin

Psalm 107 describes sailors reeling in a storm until their wisdom fails them. The late Middle English Wycliffe tradition renders the idea as all their wisdom being devoured; later English Bibles turned that image into being at one's wits' end. The medieval witness therefore supplies the underlying English idea, not the exact modern wording. Here wits means mental resources or practical understanding, not jokes or verbal cleverness.
