This is the 1952nd most frequent German word.
empfiehlt
"Empfiehlt" means "recommends" in English.
In this sentence, 'empfiehlt' is used as the third-person singular indicative form of the verb 'empfehlen', meaning 'recommend'. It describes the teacher's action of suggesting something beneficial.
Der Lehrer empfiehlt ein gutes Buch für das Lernen.
The teacher recommends a good book for learning.
'Empfiehlt' here functions similarly, being part of the verb 'empfehlen' and indicating the friend's suggestion for an activity (watching a movie).
Meine Freundin empfiehlt, diesen Film anzusehen.
My friend suggests watching this movie.
Again 'empfiehlt' denotes the act of recommending as part of daily advice, showing its usage in habitual suggestions.
