Unfeigned is an adjective that means genuine or sincere. 

The root word of unfeigned is feign, a word of Latin origin that means to invent or pretend. Our word of the day adds the prefix U-N which means ‘not.’ If something is unfeigned, it’s not invented or pretended. In other words, it’s real or honest. Here’s an example of unfeigned in use:

When I developed a cold on the day of our big history test, my parents suspected I was faking. After taking my temperature, they learned my illness was unfeigned — but still the product of good timing.
