The phrase "art born with" implies a natural talent or inclination towards a particular artistic skill. Antonyms for this phrase would include "artificially learned," "unskilled," "inept," or "uncreative." Instead of being born with an innate talent, these antonyms suggest that the skill has been acquired through practice and dedication, or that the individual lacks the ability to create something of artistic value. However, it's important to note that these antonyms do not negate the potential for someone to develop their artistic skills over time, regardless of whether or not they were born with a natural knack for it.
