Misbegotten

Misbegotten is an adjective that means badly conceived or planned. 

The Middle English word ‘beget’ means ‘to produce offspring.’ Our word of the day originally referred to people who were born out of wedlock. But more recently, it refers to ideas or things that weren’t planned well. For example:

My plans to have an office party were horribly misbegotten. Not only did I not properly plan the entertainment, but I didn’t realize that a pool party in December wouldn’t make much sense in Minnesota.
