Vegetables or fruits preserved in brine, vinegar, or similar acidic solution; difficult or awkward situations (informal).
From Middle Dutch pekel or Middle Low German pókel, meaning 'brine, salt water.' The preservation technique spread throughout Europe and became essential for long sea voyages. The figurative sense of 'difficult situation' emerged in the 16th century.
Pickles represent one of humanity's oldest biotechnologies - we learned to harness beneficial bacteria and acid to preserve food thousands of years before understanding the science behind it. The phrase 'in a pickle' comes from the idea of being preserved in an uncomfortable solution, perfectly capturing how we feel when stuck in tricky situations.
