The word "reachier" does not exist in the English language, therefore it does not have any antonyms. However, if we were to assume that the intended word was "reacher", which means someone or something that reaches or extends, then we can identify some antonyms. Antonyms for reacher could include words such as shorter, retractable, withdrawable, or limited. These words express the opposite meaning of reacher, which is to contract or shorten instead of extend or stretch out. It is important to use proper spelling and vocabulary to avoid confusion and ensure clear communication.
