Polish verb BYĆ – to be. Without hundreds of extra words, look how to conjugate it in present, past and future tense.
BYĆ – to be
| Ja jestem | I am |
| Ty jesteś | You are |
| On, ona, ono jest | He, she, it is |
| My jesteśmy | We are |
| Wy jesteście | You are(plural) |
| Oni, one są | They are |
What is the difference between Oni and One? The difference is in gender. Oni is when we tell about men, or men with women. One is when we tell about only women:
On+on = Oni
On+ona = Oni
Ona+Ona = One
Now look how to conjugate BYĆ in past tense. It can be complicated at first sight, because past tense is fully gender based.
| Ja byłem Ja byłam | I was (a man says) I was (a woman says) |
| Ty byłeś Ty byłaś | You were (said to a man) You were (said to a woman) |
| On był Ona była Ono było | He was She was It was |
| My byliśmy My byłyśmy | We were (m+m or m+w) We were (w+w) |
| Wy byliście Wy byłyście | You were (m+m or m+w) You were (w+w) |
| Oni byli One były | They were (m+m or m+w) They were (w+w) |
And in future tense. It is much easier, future tense is not gender based.
| Ja będę | I will be |
| Ty będziesz | You will be |
| On, ona, ono będzie | He, she, it will be |
| My będziemy | We will be |
| Wy będziecie | You will be |
| Oni, one będą | They will be |
And also, look at formal words “Mr.”, “Mrs.” that are needed to talk politely with a person whom you don’t know. Verbs with these pronouns are conjugated like with pronouns On, ona, ono.
Pan – Mr.
Pani – Mrs.
Panowie – Nr. (plural)
Panie – Mrs. (plural)
Państwo –Mr. and Mrs. (plural)
There are some mistakes:
It is: Ja byłam (should be: Ja byłem) – I was (a man says)
My byłyśmy (My byliśmy) – We were (m+m or m+w)
My byliśmy (My byłyśmy) – We were (w+w)
One były – They were (w+w) also (it+it=One)
