This word makes a sentence a question. It is like putting a question mark at the end.

Let's think one more time about whether this is really okay.
When you use か at the end of a sentence, it can sound strong or like a man speaking. Men often use it with friends. Women usually just raise their voice to ask a question. You can also use か to ask yourself a question.
This is different from how you make questions in English. In Japanese, the word before 'か' changes how polite your question sounds. If you use a plain word before 'か', it is very casual. If you use 'ます' or 'です' before 'か', it is polite. Using casual 'か' in a polite talk can seem rude.
Don't use this when asking a polite question. For example, say '学生ですか' not '学生か'. When you ask a question, you add 'か' to the end of a sentence. If the sentence ends with 'だ', you take 'だ' away. Then you add 'か'. For example, '学生だ' means 'is a student'. To ask 'Is it a student?', you say '学生か'. You do not say '学生だか'. Another example is '静かだ'. This means 'is quiet'. To ask 'Is it quiet?', you say '静かか'.
