Questions & Answers about Ekser i tipl su pored čekića.
Su is the 3rd person plural form of biti (to be) in the present tense, so it means are.
The subject is Ekser i tipl = the nail and the wall plug/dowel, which is a plural idea because it refers to two things. That is why Serbian uses su, not je.
- ekser = nail
- tipl = wall plug / anchor / dowel
- su = are
So the structure is literally:
Ekser i tipl su ... = The nail and the wall plug are ...
Because ekser i tipl are the subject of the sentence, so they stay in the nominative case, which is the dictionary/basic form here.
But čekića comes after the preposition pored, and pored requires the genitive case.
So:
- ekser = nominative singular
- tipl = nominative singular
- čekića = genitive singular of čekić
This is very common in Serbian: prepositions often force a specific case.
