Dacă frâna nu merge bine, las bicicleta în parcare și iau tramvaiul.

Dacă means if and introduces a condition.

In this sentence, the first part gives the condition:

• Dacă frâna nu merge bine = If the brake doesn’t work well

The second part gives the result:

• las bicicleta în parcare și iau tramvaiul = what the speaker does if that condition is true

So the basic pattern is:

• Dacă
  • condition, + result

Because frâna is the definite form of frână.

• frână = a brake
• frâna = the brake

Romanian usually adds the definite article to the end of the noun instead of putting a separate word like the in front.

So:

• frână → brake
• frâna → the brake

This is very common in Romanian:

• bicicletă → bicicleta
• tramvai → tramvaiul

That is a very common question. Romanian a merge has a wider meaning than English to go.

It can mean:

• to go
• to walk
• to function / to work

So:

• Tramvaiul merge repede. = The tram goes fast.
• Aparatul nu merge. = The machine doesn’t work.
• Frâna nu merge bine. = The brake doesn’t work well.

In this sentence, merge clearly means functions or works.

Because bine is an adverb, and it modifies the verb merge.

• bun / bună = good (adjective, used with nouns)
• bine = well (adverb, used with verbs)

Here, the idea is not that the brake is good, but that it works well.

Compare:

• o frână bună = a good brake
• frâna merge bine = the brake works well

So bine is the correct choice.

Romanian often uses the present tense in both parts of this kind of real, possible condition.

So:

• Dacă frâna nu merge bine, las bicicleta...

can express:

• a habitual action: Whenever the brake doesn’t work well, I leave the bike...
• or a future result in context: If the brake doesn’t work well, I’ll leave the bike...

This is normal Romanian usage. The present tense can cover both a general truth and a near-future result, depending on context.

Because bicicleta is the direct object of las (I leave).

In Romanian, direct objects often appear with no preposition:

• citesc cartea = I read the book
• iau tramvaiul = I take the tram
• las bicicleta = I leave the bicycle

English learners sometimes expect a marker, but Romanian usually does not need one here.

You may know that Romanian sometimes uses pe with direct objects, but that is mainly with:

• people
• highly specific animate beings
• certain emphatic cases

Since bicicleta is an inanimate thing, no pe is used here.

Because the sentence treats them differently in terms of specificity.

• bicicleta = the bicycle
• tramvaiul = the tram
• în parcare = in/at a parking area / in the parking lot

Romanian often leaves a place noun indefinite when the speaker means the location in a general way rather than a specifically identified one.

So:

• las bicicleta în parcare sounds like leaving the bike in the parking area / parking lot
• iau tramvaiul sounds like taking the tram as the known means of transport in that situation

This difference is very natural in Romanian.

Because în is the most natural choice when you mean in or inside a parking area / parking lot.

• în parcare = in the parking lot / in the parking area

Romanian often uses în for enclosed or defined spaces.

Sometimes la can be used for being at a place in a broader sense, but here în parcare is the normal phrasing if the idea is that the bicycle is left there physically inside that area.

Because the sentence begins with a conditional clause introduced by Dacă.

Romanian normally separates that introductory clause from the main clause with a comma:

• Dacă frâna nu merge bine, las bicicleta în parcare și iau tramvaiul.

This is similar to English:

• If the brake doesn’t work well, I leave the bike...

So the comma marks the boundary between:

1. the condition
2. the main action

Because a lua is an irregular verb in the present tense.

The first person singular is:

• eu iau = I take

Other common forms are:

• tu iei = you take
• el/ea ia = he/she takes
• noi luăm = we take
• voi luați = you take
• ei/ele iau = they take

So iau tramvaiul means I take the tram.

This verb is very common, so it is worth memorizing early.

Yes. Și simply means and.

It links the two actions:

• las bicicleta în parcare
• iau tramvaiul

So:

• las bicicleta în parcare și iau tramvaiul = I leave the bicycle in the parking area and take the tram

It is the standard coordinating conjunction for joining words, phrases, and clauses.

It can describe either one, depending on context.

With the present tense, Romanian allows both readings:

1. Habitual / general

   • Whenever the brake doesn’t work well, I leave the bike and take the tram.

2. Specific future-like situation

   • If the brake doesn’t work well, I’ll leave the bike and take the tram.

Without extra context, both are possible. The present tense in Romanian is flexible in this kind of sentence.
