From Middle English lopster (“lobster"), from Old English loppestre (“lobster, spider-like creature"), believed to be a corruption of Latin locusta (“lobster, locust") + the Old English feminine agent suffix -estre; or from Old English lobbe, loppe (“spider") + the Old English feminine agent suffix -estre, equivalent to lop +"Ž -ster.
