Being a good runner, or having unusual aptitude in that area, can be considered a trait
No, "boy" would not be considered a trait. "Boy" refers to a person's gender, specifically a male child or young male. Traits are characteristics or qualities that describe someone's personality, behavior, or physical appearance. Some examples of traits could be honesty, kindness, intelligence, or having blue eyes. To determine traits, you would typically consider various attributes or qualities that describe a person, rather than simply their gender.
