A kangaroo word is a word that contains one of its own synonyms inside of it. The word "masculine" for example has the word "male" in it. The letters of the snynoym have to be arranged in the right order, but they may be separated. Another example would be the word "appropriate", which has the three letters a, p and t in it, forming "apt", a synonym of the word appropriate.

Here, Google's AI claims that the word "Beobachten" has all the letters of its synonym "sehen".

Also "Renovieren" supposedly has the letters n, e and u inside of it, forming "neu".

Oh well...
