A tool with a cylindrical or pointed end used to remove the central part of something, like the seeds from an apple or apple juice from concentrate.
From 'core' + '-er' (agent suffix). The apple corer became a standard kitchen tool in the 19th century, and the word generalized to describe any tool with this function.
The humble apple corer is a engineering marvel—it solves the problem of removing seeds without wasting fruit, and the same principle appears in medical instruments for biopsies and geological sampling.
