Definition of whack

The word "whack" as a verb, meaning to hit forcefully, has an interesting history that dates back to the late 16th century. Its origin is uncertain, but some linguists suggest that it may derive from the Dutch word "want," which had the same meaning. Other theories trace its roots to the Middle English "hwac," meaning a blow or a slit. The Latin-based word "viz" was also used similarly in Old English, and it's possible that "whack" evolved from a blend of "viz" and "want." Some scholars also point to possible links to the Middle Dutch word "hakke," meaning an axe or an axe blow, or the Middle Low German word "hakken," meaning to chop or break. Although the exact origin of "whack" is debated, its meaning has remained consistent: to strike something with force. This usage became popular in the late 16th century, and by the mid-19th century, "whack" had also taken on the meaning of "an emphatic or enthusiastic expression or exclamation" in British English. In modern English, the verb "whack" is still used in this sense, as well as to describe a sharp blow, particularly in sports and games. For example, a golf swing may result in a "whack" against the ball, or a basketball player might "get whacked" while trying to make a shot.
