Questions & Answers about По-моему, этот аргумент меняет вывод.
Why is there a hyphen in по-моему?
Adverbs formed from adjectives or pronouns using the prefix по- and the dative endings -ому or -ему are always hyphenated. It literally translates to 'according to my opinion'.
Does аргумент mean the same thing as a verbal fight?
No, it is a partial false friend. аргумент only refers to a logical reason, point, or piece of evidence used to prove a conclusion. If you want to talk about an emotional verbal fight or quarrel, you should use ссора or спор.
Why doesn't the ending of вывод change if it is the direct object of the verb?
The word вывод is indeed in the accusative case here because it is the direct object being changed. However, for masculine inanimate nouns, the accusative form looks exactly the same as the nominative dictionary form.
Why is there a comma after по-моему?
In Russian, introductory words and phrases that express the speaker's personal attitude, opinion, or source of information must be separated from the rest of the sentence by commas.
