Etymology

Origin of misbegotten

First recorded in 1540–50; mis- 1 + begotten

Explanation

If you describe something as misbegotten, you think it had an improper basis or was poorly conceived — like the misbegotten dress code at your school, which requires students to wear long sleeves even in hot, humid weather. The adjective misbegotten, which commonly means "badly planned," used to have another use: it was a derogatory way to describe someone born to unmarried parents. It's extremely old fashioned to use the word that way, but you may come across it in an older book — describing a misbegotten heroine, for example. Misbegotten can also be used simply to mean "contemptible," as in "That misbegotten villain stole my grandmother's purse!"
