Questions & Answers about Нужно учить новые слова каждый день.
What does «нужно» mean in this sentence?
«Нужно» is an impersonal modal word meaning “it is necessary” or “one needs to.” There is no explicit subject. If you want to specify who needs it, you’d add a dative pronoun, e.g. «Мне нужно учить новые слова каждый день» (“I need to learn new words every day”).
Why is the verb «учить» in the infinitive form?
After impersonal modals like «нужно», the action is expressed by an infinitive. Infinitive + modal = “to have to do something.”
Why use the imperfective aspect «учить» instead of the perfective «выучить»?
Imperfective verbs (учить) describe repeated or ongoing actions—here: the habit of learning daily. If you used the perfective «выучить», it would imply completing the learning in one shot (e.g. “to learn all the words completely, once and for all”).
Why are «новые слова» in the accusative case?
«Слова» is the direct object of the transitive verb «учить», so it takes the accusative. Because «слова» is an inanimate plural noun, its accusative form is identical to the nominative («слова»). The adjective «новые» matches this form.
Can I swap the word order to emphasize something?
