Learn Dutch: Tijdens het experiment deed het algoritme ons iets raars beseffen. - During the experiment, the algorithm made us realize something weird.

This highlights the core difference between doen and laten as causative verbs. We use doen here because the algorithm triggers an involuntary, internal mental reaction (realizing something). You use laten when someone is allowed, consciously instructed, or delegated to do a physical action. Since an algorithm cannot literally instruct you to realize something, doen is the only correct choice for this spontaneous internal shift.

Why does the adjective raars have an -s at the end?

In Dutch, when an adjective immediately follows an indefinite pronoun like iets (something), niets (nothing), veel (a lot), or wat (something), the adjective takes an extra -s. Because it follows iets, the base adjective raar (weird) becomes iets raars (something weird).

Why is the word order deed het algoritme rather than het algoritme deed?

This is a quick refresher on inversion. Because the sentence begins with the time phrase Tijdens het experiment (During the experiment) instead of the subject, the subject (het algoritme) and the conjugated verb (deed) must swap places to keep the main verb in the second grammatical position of the sentence.

Why is there no before at the end of the sentence?
