Ludwig's WRAP-UP
In conclusion, "slow-witted" is a well-established compound adjective used to denote a lack of mental agility or intelligence. Ludwig AI confirms that the phrase is grammatically correct and widely used across a variety of high-quality English sources. While it is predominantly found in News & Media to describe characters, politicians, or even sluggish technology, writers should be mindful of its potentially derogatory tone.
