To give strength or muscular power to something; to make strong or muscular.
Combining 'em-' (to make or put into) with 'brawn' (muscular strength), this word is primarily archaic or dialect. It follows the productive verb-forming pattern seen in English since Middle English.
While this word is almost extinct in modern English, it reveals how people once thought about strength—not just as a state, but as something you could literally 'put into' someone through training or magic.
