Questions & Answers about Muszę jechać taksówką, żeby się nie spóźnić.
Why is it taksówką instead of just taksówka?
When expressing the means of transport you use to travel, Polish uses the Instrumental case. The feminine noun taksówka (taxi) changes its ending to -ą, giving us taksówką (by taxi).
Since we are learning arrival verbs like przyjechać, could I say muszę przyjechać taksówką here?
You could, but it changes the meaning slightly. Jechać focuses on the journey or the method of travel itself (I must take a taxi). If you used the arrival verb przyjechać, it would mean 'I must arrive by taxi', focusing entirely on reaching the destination rather than the ride itself.
How does żeby work in this sentence?
Żeby means 'in order to'. Because the person doing the action is the same in both halves of the sentence (I must go, I don't want to be late), żeby is simply followed by a verb in the infinitive form, which is spóźnić się here.
Why is się placed before nie spóźnić rather than at the end?
The reflexive pronoun się is a short, weak word that prefers to hide in the middle of a sentence. It naturally avoids being at the very end of a phrase. Placing it before nie spóźnić sounds much more natural in Polish than saying żeby nie spóźnić się.
