Why is a pickle called and not pickled cucumber?

Pickles are called pickles because they are preserved in a pickling solution, which is typically a mixture of vinegar, salt, and spices. The word "pickle" comes from the Dutch word "pekel", which means "brine". Cucumbers are the most common type of vegetable that is pickled, but other vegetables, such as carrots, onions, and peppers, can also be pickled.
