Questions & Answers about Мой дедушка был солдатом.
Why is it Мой дедушка and not Моя дедушка if the word ends in -а?
Even though дедушка ends in -а, which is normally a feminine ending, it refers to a male person. In Russian, nouns describing men are grammatically masculine regardless of their ending. Because of this, any adjectives or pronouns attached to the word must also take the masculine form, which is why we use мой.
Why is the word for soldier in the instrumental case (солдатом) instead of the nominative (солдат)?
When using the past tense of быть (to be) to describe someone's profession, role, or status, Russian almost always puts that role in the instrumental case. It highlights that being a soldier was a phase, job, or a specific role during his life rather than his fundamental identity.
Would it be completely wrong to say Мой дедушка был солдат using the nominative case?
It is not strictly wrong, and you might hear native speakers use it in casual, everyday speech, but it sounds less polished. The nominative case with the past tense of быть usually implies a permanent, timeless characteristic. For professions and temporary life stages, using the instrumental case is the standard grammatical rule you should practice.
