Questions & Answers about Zrobiliśmy to, by polepszyć jakość.
How is the verb polepszyć formed in this sentence?
It is built from the comparative adjective lepszy (better). By adding the prefix po- and the verb ending -ć, it literally becomes 'to make better' or 'to improve'. This shows a completed change of state, making it a perfective verb.
Since polepszyć is perfective, what is its imperfective equivalent?
The imperfective pair is polepszać. You cannot just remove the prefix because lepszyć is not used as a standalone verb in modern Polish. Changing the suffix from -yć to -ać is the standard way to form imperfective pairs for these adjective-derived verbs.
Is there a reason to use by here instead of żeby?
There is no difference in meaning; by, żeby, and aby all mean 'in order to'. By is simply a slightly shorter, sometimes more literary or formal alternative to the everyday żeby.
Why doesn't the noun jakość change its ending, since it is the direct object?
As the direct object of polepszyć, jakość is indeed in the accusative case. However, it belongs to a specific category of feminine nouns that end in a soft consonant. For these nouns, the accusative form looks identical to the nominative.
