Questions & Answers about Imam samo jedan problem.
Why use jedan for the number one here? Does it change depending on the word it goes with?
Since problem is the object of the verb imam, shouldn't its ending change?
It actually is in the object case (accusative)! However, for masculine things that are not alive, the object form looks exactly the same as the basic dictionary form. So both jedan and problem keep their basic spelling here.
Where is the word for 'I' in this sentence?
The word ja (I) is dropped. In Croatian, the ending of the verb tells you who is doing the action. Since imam specifically means 'I have', you do not need to add the pronoun unless you want to sound emphatic.
Is the word samo always placed before the number?
It is best to keep samo (only) right before the word or phrase it focuses on. Placing it right before jedan problem makes it clear that you are emphasizing the quantity of the problem.
