Learn Croatian: To je, naime, samo optička varka. - You see, this is just an optical illusion.

In this sentence, naime acts as a parenthetical discourse marker inserted into the clause. The enclitic verb je must stay in the strict second position, right after the first word To. Once the enclitic is safely in its required spot, naime can be dropped in to add explanatory flavor, separated by commas because it lightly interrupts the natural flow of the sentence.

Could we put naime at the very beginning of the sentence instead?

Yes, you can absolutely say Naime, to je samo optička varka. When naime is at the beginning, it is followed by a comma, and the rest of the sentence proceeds normally. The enclitic je still attaches to the first available word in the main clause, which remains to.

The English translation says 'You see', but doesn't naime mean 'namely'?

While naime translates literally to 'namely', it is used much more frequently in Croatian than in English as a conversational linking word. It introduces an explanation or a clarification of whatever was just said. In natural spoken English, we usually express this explanatory tone with phrases like 'you see', 'the thing is', or 'in fact'.

Why do we use the neuter pronoun To when varka is a feminine noun?
