Did you know?

The origins of lambaste (which can also be spelled lambast) are somewhat uncertain, but the word was most likely formed by combining the verbs lam and baste, both of which mean “to beat severely.” (This baste is unrelated to either the sewing or cooking one.) Although lambaste started out in the 1600s meaning “to assault violently,” English speakers were by the 1800s applying it in cases involving harsh attacks made with words rather than fists. This new sense clearly struck a chord; after fighting its way into the lexicon, lambaste has held fast ever since.
