De ouders zijn elkaar aan het kussen.

Questions & Answers about De ouders zijn elkaar aan het kussen.

What exactly does elkaar do in this sentence?
Elkaar means "each other". It is a reciprocal pronoun, which simply means it shows an action goes both ways: one parent is kissing the other, and vice versa.
Why do we say zijn ... aan het kussen instead of just kussen?
The zijn aan het plus infinitive structure is the Dutch way to show that an action is currently in progress. It translates directly to the English continuous tense "are kissing" rather than just "kiss".
Why is elkaar placed in the middle of the sentence instead of at the end?
When using the Dutch aan het structure, the direct object (in this case, elkaar) must go between the conjugated verb (zijn) and aan het. You cannot put it at the very end like you do in English; saying zijn aan het kussen elkaar is incorrect.
I have seen the word kussen used to mean "pillows". How do I know it is a verb here?
The grammar structure gives it away! The phrase aan het is always followed by an infinitive verb. Because of this rule, you instantly know kussen is the verb "to kiss" rather than a plural noun.
