Questions & Answers about Der Baum fällt nur, weil der Biber ihn gefällt hat.
Why does the sentence use fällt and then gefällt? Are they forms of the same verb?
No, they are a classic transitive/intransitive pair. fällt is the present tense of fallen (to fall), which is a strong, intransitive verb. gefällt here is the past participle of fällen (to fell/cut down), which is a weak, transitive verb.
Is there a trick to remembering which of these paired verbs is strong and which is weak?
Yes! In German, when a verb has both an intransitive version (an action happening on its own) and a transitive version (doing the action to a direct object), the transitive one is almost always weak. Since the beaver is doing the action to an object (ihn), fällen is weak, which is why its participle ends in -t (gefällt). The intransitive fallen is strong, so its participle ends in -en (gefallen).
Doesn't gefällt usually mean 'pleases', as in Das gefällt mir?
It often does, but context is key here! The verb gefallen (to please) conjugated for he/she/it is indeed gefällt. However, in this sentence, we are looking at a perfect tense verb at the end of the clause: gefällt hat. Here, gefällt is the past participle of fällen (to cut down), not the present tense of gefallen.
Why does the sentence use when the English translation says 'it'?
