<div class='writeup-body'>One of the common uses of the particle か is often translated to 'or' in English. While this translation is accurate, it is not actually any different from か's regular usage as a question marker.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>それはお母（かあ）さんの靴（くつ）かお父（とう）さんの靴（くつ）。</div><div class='writeup-example--english'>Are those mom's shoes, or dad's shoes?</div></li><li class='writeup-example'><div class='writeup-example--japanese'> それはお母（かあ）さんの靴（くつ）か。お父（とう）さんの靴（くつ）か。</div><div class='writeup-example--english'>Are those mom's shoes? Dad's shoes?</div></li> </ul>From these examples, we can see that, in Japanese, か is performing the same role that a question mark would, or that a change in tone of voice would in spoken language. 'Would you like tea? coffee?' (said with a rising tone) This nuance of か can be used after the dictionary form of almost any word in Japanese. However, using です or ます will change the nuance from 'presenting possibilities', to 'asking a formal question', so should be avoided.<ul class='writeup-examples--holder'> <li class='writeup-example'><div class='writeup-example--japanese'>今日（きょう）か明日（あした）休（やす）むか。</div><div class='writeup-example--english'>Today or tomorrow, when will I take a break? (The speaker is thinking this to themselves)</div></li><li class='writeup-example'><div class='writeup-example--japanese'>今日（きょう）か明日（あした）は休（やす）みますか。</div><div class='writeup-example--english'>Will you take a break today or tomorrow?
