Questions & Answers about Var är taxin? Chauffören väntar på oss.
Why do we use var here instead of vart?
The word var asks about a static position ('where at'), while vart asks about a destination or movement ('where to'). Because we are asking for the taxi's current location, not where it is driving to, we must use var.
Why is it väntar på instead of väntar för to mean 'waiting for'?
Prepositions rarely translate perfectly between English and Swedish. In Swedish, the verb väntar (to wait) pairs with the preposition på when you are waiting for someone or something. Saying väntar för is a common mistake for English speakers, so it helps to memorize väntar på as a set phrase.
Why is the definite form taxin and not taxien?
The base noun is en taxi. For en words that end in a vowel, Swedish simply adds an -n to make the word definite, rather than the full -en, which would create an awkward double vowel.
What is the base form of chauffören?
The base form is en chaufför (a driver). Since it is an en word ending in a consonant, it takes the standard -en suffix to become definite (chauffören). Note that because it is a French loanword, the 'ch' is pronounced like an English 'sh' sound.
