Why is the past tense of raadplegen written as one word (raadpleegde) instead of separating like a split verb (pleegde raad)?
Raadplegen (to consult) is an inseparable back-formation. It was formed backwards from the noun raadpleging (consultation) rather than by gluing together the noun raad and the verb plegen. Because it's not a true compound verb, it doesn't separate. The past tense is simply raadpleegde, and its past participle is geraadpleegd (never raadgepleegd).
The verb plegen is normally a strong verb. Why does raadplegen get the regular weak ending -de here?
This is a key feature of back-formations! Even if they end in a verb that is normally strong, verbs created through back-formation almost always behave as weak (regular) verbs. Therefore, it takes the standard -de past tense ending to become raadpleegde, rather than using a strong past tense form.
Could I use studeert instead of bestudeert for studying the solar system?
No, you need bestuderen here. In Dutch, studeren is generally intransitive and refers to the general act of being a student or doing a degree (like studying at university). Bestuderen is transitive, meaning it requires a direct object, and is used when you closely examine, analyze, or investigate a specific thing, like het zonnestelsel.
Why does zonnestelsel have an -en- in the middle?
When forming compound nouns in Dutch, you often need a linking sound. The rule is that if the first part of the compound (zon) only has a plural form ending in -en (zonnen), you use -en- as the glue to attach it to the second word (stelsel).
