Questions & Answers about Peta na ovoj sandali je vrlo udobna.
Wait, doesn't peta mean fifth?
Yes, peta is the feminine form of the ordinal number fifth. However, it is also a noun meaning heel (both the body part and the shoe part). You can tell it is a noun here because it acts as the main subject of the sentence.
Why do we use the preposition na instead of u with sandali?
We use na (on) because the heel is a component attached to the exterior of the shoe. While you put your foot u (in) a shoe, the physical parts of the shoe itself are located na (on) it. The preposition na for location puts ovoj sandali in the locative case.
Could I use jako instead of vrlo in this sentence?
Yes, jako and vrlo are interchangeable here to mean very. Vrlo is slightly more formal and is exclusively used to intensify adjectives or adverbs, whereas jako is extremely common in everyday speech and can also be used to mean strongly.
Why is the adjective udobna in the nominative case, rather than matching the locative sandal?
The adjective udobna (comfortable) describes the subject of the sentence, peta (the heel), not the sandal. Because peta is a feminine noun in the nominative case, udobna must also be in the feminine nominative form to agree with it.
