Questions & Answers about Nie będę kosić trawnika bez nowej kosiarki.
How is the word kosiarka formed in this sentence?
It is built from the verb kosić (to mow) by adding the suffix -arka. This suffix is extremely productive in Polish for creating nouns that denote machines and tools (nomina instrumenti) from verbs. Other common examples you might know are zmywarka (dishwasher, from zmywać) and suszarka (hair dryer, from suszyć).
Why is the word for lawn trawnika instead of trawnik?
Because the sentence is negative (nie będę kosić). Normally, the verb to mow takes a direct object in the Accusative case (kosić trawnik). However, in Polish, whenever a verb with an Accusative direct object is negated, that object must switch to the Genitive case.
What dictates the grammatical case of nowej kosiarki?
The preposition bez (without) always requires the noun phrase that follows it to be in the Genitive case. Because of this, the basic Nominative phrase nowa kosiarka becomes nowej kosiarki.
Could I say nie będę kosił instead of nie będę kosić here?
Yes! To form the future imperfective tense in Polish, you combine the future forms of być (like będę) with either the infinitive of the verb (kosić) or its third-person past tense form (such as the masculine kosił or feminine kosiła). Both constructions are completely natural and mean the exact same thing, though using the infinitive hides the speaker's gender.
