Questions & Answers about Ne mogu dugo sjediti u uredu.
Because mogu is a modal verb meaning I can, and sjediti is the main verb meaning to sit.
So the structure is:
- ne mogu = I cannot / I can’t
- sjediti = to sit
This is very similar to English:
- I can sit
- I can’t sit
After a modal verb in Croatian, the next verb is usually in the infinitive:
- Mogu doći. = I can come.
- Ne mogu spavati. = I can’t sleep.
- Ne mogu dugo sjediti. = I can’t sit for long.
In Croatian, the negative particle ne is usually written separately from the verb:
- ne mogu = I cannot
- ne znam = I do not know
- ne radim = I am not working / I do not work
So ne mogu is the normal spelling.
English learners sometimes expect one word because English has cannot, but Croatian does not work that way here.
