Breaking Down Aftermath

At first glance, one might calculate aftermath to be closely related to mathematics and its cropped form math. But the math of mathematics (which came to English ultimately from Greek) and the math of aftermath grew from different roots. Aftermath dates to the late 1400s and was originally an agricultural term, an offshoot of the ancient word math, meaning “a mowing.” The original aftermath came, of course, after the math: it was historically the crop cut, grazed, or plowed under after the first crop of the season from the same soil. (Math is still used in some parts of the United Kingdom to refer to a mowing of a grass or hay crop, as well as to the crop that is mowed.) It wasn’t until the mid-1600s that aftermath came to have the meanings now familiar to us, referring to the period of time following a destructive event, or to a negative consequence or result.

Etymology

Old English mæth "mowing," from māwan "to mow"

Word Origin
The second part of aftermath comes from the Old English word mæth, meaning "the result of a mowing or harvesting," that is, a crop. This word was derived from the Old English verb māwan, which survives today as our modern English mow. During a good growing season in England, a second and sometimes a third crop of hay could be grown after the first mowing. When this crop was cut, it was the aftermath. Since the 17th century, the meaning of aftermath has broadened to include all kinds of results, not just those of a second mowing.
