When it comes to Grooming, English differs from German in two respects. First, instead of using a simple verb like German "duschen," English often uses a phrasal verb, where a meaningful noun ("shower," "bath") combines with a 'light' verb ("take").
"I take several showers a day." - "Ich dusche mich mehrmals am Tag."
Second, while German expresses the Patient as though it is directly affected by the verb (as a direct or indirect object), English construes this participant more as a possessor of the body part (with a possessive pronoun).
"I brush my teeth." – "Ich putze mir die Zähne."
"I brush his teeth." – "Ich putze ihm die Zähne."
