Questions & Answers about Hij haalt het wisselgeld en plaatst de rekken.
Why is there no subject after en in this sentence?
This is an example of conjunction reduction (samentrekking). Because the subject Hij performs both actions and has the exact same grammatical role in both clauses, it can be dropped after en to avoid repetition.
What are the exact rules that allow Hij to be dropped here?
To omit a word in the second clause, it must be identical to the first clause in three ways: it must have the same meaning, the same grammatical function (here, the subject), and the same grammatical form (such as singular/plural). Hij perfectly meets all three conditions.
If I chose not to drop the subject, how would the second half of the sentence look?
You would simply write ...en hij plaatst de rekken. The conjunction en links two main clauses together, so the standard Subject-Verb-Object word order applies to both halves of the sentence.
Could the verb also be omitted if it were exactly the same in both clauses?
Yes! If he were fetching both the change and the racks, you could say Hij haalt het wisselgeld en de rekken. The verb haalt would be omitted in the second part because it shares the exact same meaning, function, and form.
