Questions & Answers about Поезд ушёл без пассажиров.
Wait, ушёл is for leaving on foot. Why does a train leave "on foot" instead of using a verb for vehicles like уехать?
It's a quirk of Russian! Trains, ships, and sometimes buses are traditionally spoken of as moving "on foot" (идти / уйти) rather than driving or riding (ехать / уехать). So, поезд ушёл is the completely standard way to say "the train departed."
What exactly does the prefix у- add to the verb here?
The prefix у- indicates departure or moving away from a place. When added to a verb of motion, it means "to leave." Because it creates a perfective verb, ушёл focuses on the completed result: the train has departed and is gone.
Why does the past tense verb ушёл look so different from its infinitive уйти?
The base verb идти (to go on foot) has a highly irregular past tense: шёл (masculine), шла (feminine), шли (plural). When you add a prefix like у-, you just attach it directly to those irregular past tense forms. Since поезд is a masculine noun, we use ушёл.
Why does пассажиров end in -ов?
