Questions & Answers about Dat kledingstuk, dat is erg sportief, dus draag ik het vaak.
Why do we use dat twice at the beginning, as in 'Dat kledingstuk, dat is...'?
This is left dislocation, a structure used to emphasize a topic. We pull the topic (Dat kledingstuk) to the very front of the sentence and then immediately refer back to it with a demonstrative pronoun (the second dat) before continuing the clause. Because kledingstuk is a het-word, the matching demonstrative is dat.
Why is there inversion after dus (dus draag ik) instead of standard word order (dus ik draag)?
The word dus is flexible. It can act as a coordinating conjunction, which keeps normal word order (dus ik draag...), or as an adverb. When used as an adverb at the start of a clause, it triggers inversion, putting the verb before the subject (dus draag ik...). Both are grammatically correct and mean the same thing, but the inversion often sounds a bit more natural in spoken Dutch.
Later in the sentence, why do we say draag ik het instead of draag ik dat?
The left dislocation (and the heavy emphasis that comes with using dat) only applies to the first clause. In the second clause (dus draag ik het vaak), you are just referring back to kledingstuk in a neutral way as the direct object, so you revert to the standard personal pronoun het.
Does sportief only refer to sports clothing?
