Sometimes you come across a verb that is actually not a verb: it is a noun, before which you can place an article (the, a). In Dutch, we use the infinitive when we use a verb as a noun:
|Het hebben van een huisdier is goed voor je gezondheid.
||(The) owning of a pet is good for your health.
Sometimes, we can omit the article, though of course this does not change the status of the verb (being a noun):
|Op vakantie gaan is leuk.
||Going on vacation is nice.
Don't be misled by this noun! If you consider it a verb, you will have a hard time analyzing the sentence.
