 ## Talk The Clock
 
+If you know how to count to 12, you can talk about hours; if you know how to
+count to 60, then you can talk about minutes and seconds. To ask the time, you
+use the copula with a null subject. The complement uses the interrogative
+pronoun, so there is no need for a sentence ender.

+That's a complete sentence because the verb is actually a noun being used as a
+verb which is interpreted as a [zero
+copula](https://en.wikipedia.org/wiki/Zero_copula) sentence. The subject in this
+sentence is not provided, these are called
+[null-subject](https://en.wikipedia.org/wiki/Null-subject_language) sentences.
+Whenever this happens, you have to interpret the subject from either the current
+sentence or from preceding sentences. In some cases, this ends up being "it" or
+"there" in English. In other cases, it ends up being the prior sentence's
+subject. Here, the English backtranslation would be "It is what time?".
