Questions & Answers about Мой друг ответил на письмо.
What is the function of the preposition на in the sentence?
In Russian, the verb ответить (to reply) is conventionally used with the preposition на when referring to a specific letter or question. Here, на письмо indicates the object to which the reply is directed—much like “replied to the letter” in English. The preposition combines with the accusative case to show the target of the action.
What case is the noun письмо in, and how can we tell?
Письмо is in the accusative case. Although for many neuter nouns the nominative and accusative forms are identical, the presence of the preposition на tells us that the noun is being used in a context that requires the accusative. This usage is common with directional or target-related actions in Russian.
What aspect and tense is the verb ответил in, and why is that significant?
The verb ответил is in the past tense and uses the perfective aspect. This means that the action of replying is viewed as complete. In Russian, perfective verbs are used to indicate completed actions, contrasting with the imperfective aspect (e.g., отвечал), which would emphasize an ongoing or habitual process rather than a finished act.
How does the possessive adjective мой function in this sentence?
Мой means “my” and it directly modifies друг. In Russian, adjectives and possessive pronouns must agree with the noun they modify in gender, number, and case. Since друг is masculine, singular, and in the nominative case, мой is also in the masculine, singular, nominative form.
How would the sentence change if “friend” referred to a female rather than a male?
If the friend were female, both the noun and the related words would need to reflect the change in gender. The noun for a female friend is commonly подруга. Accordingly, the possessive pronoun becomes моя (feminine form of “my”), and the verb takes the feminine ending, changing ответил to ответила. The sentence would then read: Моя подруга ответила на письмо.
