Questions & Answers about Zajmujemy się biznesem, ponieważ jest opłacalny i przewidywalny.
How are the adjectives opłacalny and przewidywalny formed from their verbs?
Both are formed by dropping the infinitive ending and attaching the suffix -alny (which functions exactly like the English suffix '-able'). Opłacalny comes from the verb opłacać się (to pay off / to be profitable). Przewidywalny comes from the verb przewidywać (to predict).
Why do these words use the -alny suffix instead of -elny?
The choice is usually linked to the verb's infinitive ending. Verbs ending in -ać (like opłacać) and -ywać (like przewidywać) almost always take -alny. The -elny suffix is more commonly used with verbs ending in -ić or -yć (though there are a few exceptions you will learn as vocabulary).
Why is the word biznes in the form biznesem here?
It is in the Instrumental case. As a reminder, the reflexive verb zajmować się (to deal with, to take care of, to be engaged in) always requires the object that follows it to be in the Instrumental case.
Why isn't there a pronoun like on (it) before jest opłacalny?
Polish frequently drops subject pronouns when the context makes the subject obvious. Here, the masculine singular endings of the adjectives opłacalny and przewidywalny make it perfectly clear that the sentence is referring back to the masculine noun biznes. Adding on would not be grammatically wrong, but it would sound unnaturally repetitive.
