Which synonym closely aligns with "reticent"?

The word "reticent" means being reserved or reluctant to speak openly. It describes someone who tends to keep thoughts and feelings to themselves rather than expressing them freely.

The choice that best aligns with this definition is "reserved." This term conveys a similar idea of holding back or being restrained in communication and emotional expression. In contrast, the other options such as "talkative," "outgoing," and "chatty" suggest a disposition of being expressive and engaging in conversation, which is the opposite of what "reticent" implies. Therefore, "reserved" effectively captures the essence of being quiet and not forthcoming, making it the correct synonym for "reticent."
