Learn Farsi: هر روز دوش می‌گیرم.

Farsi relies heavily on compound verbs. Just like in English, the standard phrase for showering is دوش گرفتن, which literally translates to to take a shower. The base verb گرفتن means to take or to get.

Is the word دوش related to the French word for shower?

Yes, دوش is a direct loanword from the French douche. Farsi borrowed many words for modern household items, clothing, and concepts from French during the late 19th and early 20th centuries.

Since there is no word for I (من) in this sentence, how do we know who is showering?

Because Farsi verb endings tell you exactly who the subject is, pronouns are often dropped. The ـم ending on می‌گیرم specifically means I. Adding من at the start is grammatically fine, but natives usually leave it out unless they want to emphasize the subject.

Does می‌گیرم translate to I take or I am taking?

It can be both! The prefix می forms both the present simple tense for habits and the present continuous tense for actions happening right now. You have to look at the context. Here, the phrase هر روز (every day) shows it is a routine, so it translates as the habitual I take.
