The adjective bashful isn’t one for the spotlight, but it’s the center of attention today! Bashful is an adjective that means “uncomfortably diffident and easily embarrassed.” This timid term suggests trepidation and awkward behavior when brought into prominence or notice. However, sometimes bashful suggests modesty and sensitivity more than fear or self-doubt.
The adjective nonchalant is used to describe someone who behaves in a coolly unconcerned manner or exudes a calm, casual air. If a person is feeling nervous or uncertain but wants to give an impression of confidence—as, for example, during a job interview or on a first date—they might try to appear nonchalant. But a nonchalant attitude in the face of serious matters or perilous circumstances can be received as chilly indifference.
Someone who is inquisitive asks a lot of questions. An inquisitive nature in many cases reflects intellectual curiosity—a generally desirable trait! However, inquisitive is sometimes used to suggest a degree of intrusiveness and inappropriateness. That said, be careful not to confuse inquisitive with inquisitorial, which, in pointing to inquisitions and inquisitors, calls to mind excessive cruelty.
