Polish Grammar - Instrumental Case - Masculine
As we saw in the last lesson we end up in the Instrumental case when we are describing who someone is - a woman, a doctor, etc. Here we'll see how masculine nouns change in the Instrumental

In the Instrumental case we make the following changes if the noun is masculine
- Adjective ending - add 'm' - dobry -> dobrym
- Noun ending - add 'em' - lekarz -> lekarzem
- A good (male) doctor - Dobry lekarz
- He is a good doctor - On jest dobrym lekarzem
So how would you say:
- I am the new (male) doctor -
- He is not the new doctor -
- Are you the new (male) doctor? -

The mental hook here is the 'm'. Both the adjective and the noun end in the 'm' we see in the middle of Instrumental
We can also see from the previous lesson that adjective and noun endings match for both feminine and masculine nouns so this is the matching case.
- A person / a human - Człowiek
Where the noun ends in a hard letter like 'k' we soften the ending by adding 'iem' instead of 'em'
- You are a clever person - Jesteś mądrym człowiekiem
We will see this 'softening' by using 'i' happening in many other places so it will become quite natural to do it. So how would you say:
- I am a clever person -
- He is a clever person -
- She is not a clever person -

Osoba czy Człowiek
'Człowiek' is used if we want to specifically say 'human'
Otherwise both are widely used in everyday conversation and are interchangeable like the English words 'an individual' and 'a person' so we need to know them both.
- I am an ecological person - Jestem ekologiczną osobą
- I am an ecological person - Jestem ekologicznem człowiekiem
Continuing to build on the table we started, here is the Instrumental rule for word endings for masculine nouns

Transfer Nominative nouns to Accusitive
In the following exercise you'll change nominative nouns to the instrumental case even though you probably do not know most of the words.
The nominative case of the noun is shown beside the text input box in brackets. Write the full sentence using the Instrumental case.
For example, the first sentence is 'He is a good son'. The Polish for 'son' is 'syn' so the correct answer is 'On jest dobrym synem'.Use 'człowiek' for 'person'.
