An inquisitive person is someone who is curious and eager to learn. Synonyms for this type of person might include inquiring, investigative, probing, nosy, or curious. Inquiring suggests a desire to get to the bottom of something, while investigative and probing imply a more systematic approach to questioning. Nosy might have a negative connotation in some contexts, but it can also suggest a person who is simply interested in the world around them. Curious, on the other hand, has a more innocent connotation and suggests a person who is naturally interested in learning new things. Regardless of which word you choose, an inquisitive person is someone with a thirst for knowledge and a willingness to explore.
