Questions & Answers about Я жду такси у вокзала.
Ждать is the infinitive (to wait). In a sentence you usually need a conjugated verb.
Я жду = I am waiting / I wait (1st person singular, present tense).
Russian has one present-tense form here: я жду. Depending on context it can translate as either I’m waiting (right now) or I wait (in general). The “continuous” meaning is often implied by context rather than a special verb form.
Такси is an indeclinable noun in Russian (a loanword). That means it usually keeps the same form in all cases:
- жду такси (accusative “what am I waiting for?”)
- нет такси (genitive “there is no taxi”)
The form stays такси.
