Questions & Answers about Potrącenie jest wysokie.

Why is it wysokie and not wysoka or wysoki?

Because potrącenie is a neuter noun in Polish, and the adjective has to agree with it in gender, number, and case.

So in the singular nominative:

• masculine: wysoki
• feminine: wysoka
• neuter: wysokie

Since the sentence is Potrącenie jest wysokie, the adjective must be wysokie.

How can I tell that potrącenie is neuter?

A very common clue is the ending -e in the dictionary form. Many Polish neuter nouns end in:

• -o
• -e
• -ę
• -um (usually loanwords)

Potrącenie ends in -e, so it is neuter.

Also, many nouns ending in -nie / -cie that are formed from verbs are neuter, for example:

• pytanie = question
• jedzenie = food / eating
• potrącenie = deduction / knocking down, depending on context
