Asking questions in Diinlang is very easy. The grammar of Diinlang resembles that of English but is more regular and simpler.
Asking a question in English often uses inversion. One says “Have you a phone?” instead of “You have a phone?”. English also makes use of “do-support” so the above inquiry might be “Do you have a phone?”. Diinlang makes use of neither mechanism, so the equivalent translation would be “Yu av je fohn?”
In fact, a Diinlang speaker would generally add the interrogative “ke” to the sentence and say either “Ke yu av je fohn?” or “Yu av je fohn, ke?” As you can see, this may occur at either the start or the end of a sentence. In the initial position you can think of it as having a similar function as “do-support”, although the literal meaning of “ke” is not “do”. At the end of a sentence it is rather like how some English speakers will add “eh?” to the end of a question. Alternately, think of it as an audible question mark.
On its own, ke means “what?” It can be combined with a number of other words to construct alternative interrogations, which would usually be used at the start of a sentence. Some of the possibilities are:
Ke? What?
Ke do? Where? (What place/ area?)
Ke per? Why (What for?)
Ke tem? When? (What time?)
Ke zem/jhen? Who? (What person?)
Ke li? How? (What manner?)
Ke jeve/un? Which one? (What each?)
Ke ving? What is that/there?
Ke vang? What is this/here?
Ke ta? How much/big?
Ke taz How many?
Note that a different word (su) is used for “who, what, which”, that when they are used as relative pronouns for connecting parts of sentence.
