Questions & Answers about Potrzeba mi więcej czasu.
Because this sentence uses a different pattern from the ordinary verb potrzebować.
- Potrzebuję więcej czasu = the most standard, everyday way to say I need more time.
- Potrzeba mi więcej czasu = a more impersonal, slightly more literary or elevated structure.
In potrzeba mi więcej czasu, potrzeba is not a normal 1st-person verb form. It is part of a fixed expression meaning roughly there is a need, for me, of more time.
So both sentences can mean the same thing, but Potrzebuję więcej czasu is more neutral in everyday speech.
Because the person who feels the need is put in the dative case in this construction.
So:
- mi = to me / for me
- nam = to us / for us
- mu = to him / for him
- jej = to her / for her
This pattern is:
potrzeba + dative person + genitive thing
Examples:
- Potrzeba mi spokoju. = I need peace.
- Potrzeba nam pomocy. = We need help.
