Questions & Answers about Tamo je glavni ulaz.
How is the noun ulaz related to the verbs of motion we are learning?
The noun ulaz (entrance) is built with the prefix u-, which means 'in' or 'into'. This is the exact same prefix used in the verb ući (to go in / to enter). As a bonus, you can probably guess that the word for 'exit' is izlaz, using the iz- prefix from izaći (to go out).
Why is the adjective glavni used instead of glavna or glavno?
Adjectives always have to match the gender of the noun they describe. The noun ulaz ends in a consonant, which tells us it is a masculine noun. Because of this, the adjective 'main' must take the masculine form glavni.
Why is the verb je placed right after tamo?
The word je (is) is an enclitic, which is a 'weak' word that must take the second position in a Croatian sentence. Since tamo (there) is the first word, je naturally falls into the second slot. You could also change the word order to Glavni ulaz je tamo, where the whole phrase glavni ulaz acts as the first block of information.
What is the difference between tamo and tu?
Both can translate to 'there' in English, but they give different distance clues. Tamo points to something further away from both the speaker and the listener. Tu is used for a location that is relatively close, often right next to the person you are talking to.
