Questions & Answers about Cijeli dan radim u uredu.

Why is there no word for I in the sentence?

Croatian usually drops subject pronouns because the verb ending already shows who the subject is.

• radim is 1st person singular of raditi (to work).
• The ending -m tells you the subject is I.

So Cijeli dan radim u uredu. literally just says All day work in (the) office, but it is always understood as I work… or I am working….
You only add ja (I) for emphasis or contrast:

• Ja cijeli dan radim u uredu, a ti si doma.
  I work in the office all day, and you’re at home.

What does cijeli mean, and why is it cijeli and not something else?

cijeli means whole, entire.

It’s an adjective, so it has to agree with the noun in gender, number, and case.

• dan (day) is masculine singular.
• In this sentence the form is accusative masculine singular, used for duration of time.

For dan, nominative and accusative look the same:

• nominative: (taj) dan je dug – that day is long
• accusative: radim cijeli dan – I work the whole day

So you get cijeli dan (masc. sg. acc.), not cijela (feminine) or cijelo (neuter).
