Questions & Answers about Gdzie jest mój szampon?
Why do we use mój instead of moja or moje here?
The word szampon is a masculine noun in Polish. Because of this, the possessive pronoun meaning "my" has to match it and take the masculine form, which is mój. If you were looking for a feminine object, like a book (książka), you would use moja.
Is szampon in its basic dictionary form here?
Yes, it is in the nominative case, which is the basic dictionary form. We use this form because szampon is the subject of the sentence - it is the thing that "is" somewhere.
Is the word order in this question exactly the same as in English?
Yes, in this specific case, the word order mirrors English perfectly: question word (Gdzie), verb (jest), possessive pronoun (mój), and noun (szampon). Polish doesn't need extra helper words to form simple questions like this.
