Which word describes a natural talent or skill?

The term "flair" denotes a natural talent or skill, often implying an innate ability to do something with ease and elegance. When someone has flair for a particular activity, it suggests that they perform it with a level of proficiency that seems effortless, as if it comes naturally to them. This quality can be observed in various contexts, such as artistry, music, sports, or even interpersonal communication, where the individual displays a distinctive skill or style.

In contrast, the other words do not capture the meaning of natural talent. "Fortify" refers to strengthening or reinforcing something, while "fluster" means to confuse or agitate someone, and "gaunt" describes a person who is thin and emaciated, often due to suffering or hunger. Therefore, "flair" is the appropriate choice as it aligns perfectly with the description of having a natural talent or skill.
