Learn Icelandic: Það er enginn úti núna. - There is no one outside now.

In Icelandic, when you are referring to 'no one' or 'nobody' in general (a person of unspecified gender), you use the default masculine singular form, enginn. Because it is used with the verb er (is), it acts as the subject and stays in the nominative case.

Why does the sentence start with Það er instead of just saying Enginn er úti?

Það er translates literally to 'It is', but here it works exactly like 'There is' in English. Icelandic frequently uses það as a placeholder or 'dummy subject' to state that something exists. This keeps the verb in the second position and pushes the real subject (enginn) later in the sentence.

I've also seen the word út for 'outside'. Why do we use úti in this sentence?

You use úti when describing a stationary location, meaning someone or something is already outside. You use út when there is motion towards the outside, like walking or running out. Since the sentence just describes where people are (or aren't!), there is no movement, so we use úti.

Doesn't Icelandic usually use ekki (not) to make sentences negative? Why isn't it used here?

You don't need ekki because the pronoun enginn already carries the full negative meaning ('no one' or 'nobody'). Adding ekki would create a double negative, so Það er ekki enginn would awkwardly mean 'There is not no one'.
