Questions & Answers about Мне легко учить новые слова утром.
Russian often uses the dative case to talk about how something feels to someone:
- Мне легко... = It is easy for me...
- Literally: To me (it is) easy to learn new words in the morning.
So:
- Мне = “to me” (dative of я)
- There is no nominative subject like я here. Instead, the whole infinitive phrase учить новые слова утром functions like the “thing” that is easy.
This is the same pattern you see in:
- Мне холодно. – I am cold. (Literally: To me it’s cold.)
- Ей трудно работать. – It’s hard for her to work.
Using Я would change the structure and meaning (see the next question).
