Which: どれ, どちら, どっち, & いずれ

<div class='writeup-body'>どれ is from the same family of words as これ, それ, and あれ. These words are called こそあど言葉（ことば） in Japanese. Unlike the other 3, which all point to a specific thing, words starting with ど are designed for enquiring about something unknown. どれ can roughly be translated as 'which' in English, and is used for enquiring about a group (of 3 or more things).<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>どれが飛（と）びますか。</div><div class='writeup-example--english'>Which one of these flies?</div></li><li class='writeup-example'><div class='writeup-example--japanese'>どれが新（あたら）しいですか？</div><div class='writeup-example--english'>Which one is new?</div></li><li class='writeup-example'><div class='writeup-example--japanese'>どれが綺麗（きれい）ですか？</div><div class='writeup-example--english'>Which one is beautiful?</div></li><li class='writeup-example'><div class='writeup-example--japanese'>どれが弟（おとうと）ですか？</div><div class='writeup-example--english'>Which one is your brother?</div></li></ul>From these examples, we can see that the particle が is often used with どれ, especially when preceding questions.
