From Middle High German boum, from Old High German boum, from Proto-Germanic *baumaz. Akin to Dutch boom, Low German Boom, West Frisian beam, English beam. Plural umlaut by proportional analogy with terms like Gast (“guest”) to Gäste (“guests”).
Baum m (genitive Baumes or Baums, plural Bäume, diminutive Bäumchen n or Bäumlein n or Bäumelein n)
Vögel nisten gerne in Bäumen. ― Birds like to nest in trees.
Bäume zählen zu den größten Lebensformen.
- Trees are one of the biggest life forms on the planet.
Baum fällt! ― Timber! (literally, “Tree falling!”)
- (nautical) boom
- In German, one generally says: Er sitzt auf dem Baum (literally “He’s sitting on the tree”), and accordingly: Sie klettert auf den Baum (literally “She’s climbing onto the tree”). The construction with in (as in English) is not entirely impossible, but it is rare. There is a chance that it may be misunderstood as “inside a hollow tree trunk”.
