Questions & Answers about Lončar može dokazati da je glina suha.
Because Croatian modal verbs usually take a bare infinitive.
- može = can / is able to
- dokazati = to prove
So može dokazati literally works like can prove in English.
Croatian does not use a separate word like English to in this structure. After moći (can), you normally just use the infinitive:
- Mogu doći. = I can come.
- Može govoriti. = He/She can speak.
So Lončar može dokazati... is the normal pattern.
Može is the 3rd person singular present form of the verb moći (to be able, can).
Here it matches lončar, which is singular:
- ja mogu = I can
- ti možeš = you can
- on/ona može = he/she can
Since lončar is one person, you use može.
