OE
A “euphemism” is a mild or indirect term substituted for one considered too harsh or blunt. Adults referred to the girl with the positive word “precocious,” which means forward or advanced for her age, whereas she really was “overly talkative,” so the blank should mean something like too talkative, or garrulous. “Skittish” could be cast as positive (excitable) or negative (unpredicable, jittery), but neither is a negative spin on “forward” nor “talkative.” The other choices are either neutral, such as “naïve,” meaning innocent or unworldly, or positive, such as “solicitous” (concerned or attentive) and “endearing” (lovable or charming). None of these choices would require a euphemistic replacement. “Impudent,” then, is the correct choice.
