Andrei declanșează blițul.

• Andrei = the subject
• declanșează = the verb
• blițul = the direct object

So the sentence has the same basic subject–verb–object order as English.

Declanșează is the 3rd person singular present tense form of the verb a declanșa.

So:

• a declanșa = the dictionary form, to trigger / to set off
• el/ea declanșează = he/she triggers, he/she is triggering

With Andrei, Romanian uses the same 3rd person singular form that it would use with he.

It can mean either, depending on context.

Romanian often uses the simple present where English might choose either:

• Andrei triggers the flash
• Andrei is triggering the flash

So declanșează does not by itself force one reading the way English sometimes does.

Because -ul is the definite article attached to the end of the noun.

• bliț = a flash
• blițul = the flash

Romanian usually puts the definite article after the noun, unlike English.

So blițul literally works like flash-the, but in natural English it is simply the flash.

Bliț is a neuter noun.

Romanian neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular definite form, a neuter noun often looks masculine:

• bliț = flash
• blițul = the flash

Its plural is:

• blițuri = flashes
• blițurile = the flashes

Because pe is usually used before direct objects that are animate, especially people.

For example:

• Îl văd pe Andrei. = I see Andrei.

But with an inanimate object like blițul, Romanian normally does not use pe:

• Andrei declanșează blițul.

So the absence of pe is completely normal here.

• Andrei is in the nominative because it is the subject.
• blițul is the direct object, so functionally it is in the accusative.

However, in Romanian, many nouns do not change form visibly between nominative and accusative. So blițul looks the same in both.

That is why learners often feel that Romanian has case, but does not always show it clearly on the noun itself.

A rough pronunciation guide:

• Andrei ≈ ahn-DRAY
• declanșează ≈ deh-klan-SHEA-zuh
• blițul ≈ BLEETS-ul

Useful letter values here:

• ș = sh as in ship
• ă = a short neutral vowel, like the a in sofa
• ț = ts as in cats

So:

• declanșează has ș = sh
• blițul has ț = ts

This is the neutral, most straightforward word order:

• Andrei declanșează blițul.

Romanian word order is fairly flexible, but changes usually add emphasis, contrast, or a more marked style.

So for learners, this sentence is best understood as the standard pattern:

• Subject + Verb + Object

A declanșa is a good, natural verb if the idea is to trigger or to set off the flash.

It can sound a bit more technical or precise than some other options.

Depending on context, Romanian might also use verbs like:

• a porni = to start
• a aprinde = to switch on / light

But declanșează blițul specifically suggests making the flash fire or go off, which matches the idea of triggering very well.
