Questions & Answers about Kupimy nowe kijki i gogle, jak tylko dojedziemy do miasta.
Why is dojedziemy in the future tense when the English translation uses the present tense "reach"?
In English, we use the present tense after "as soon as" for future events. Polish is strictly logical here: since the arriving will happen in the future, you must use the future tense (dojedziemy). Because reaching the city is a single, completed action, the sentence uses the perfective future form.
Could I use dojdziemy or dotrzemy instead of dojedziemy here?
You could absolutely use dotrzemy (we will arrive/reach), which is a great general-purpose verb. However, dojedziemy specifically means arriving by a vehicle. You wouldn't use dojdziemy here unless you were literally walking all the way to the city.
What case is nowe kijki i gogle, and why isn't the adjective ending -ych?
It is in the accusative case, as the direct object of Kupimy. Because both kijki (poles) and gogle (goggles) are inanimate nouns, they fall under the non-masculine-personal category. For these nouns, the accusative plural is identical to the nominative plural, so the adjective takes the standard non-personal ending -e (nowe) rather than the masculine personal ending -ych or -ich.
Why is there a comma before jak tylko? In English, we don't usually use one there.
