Coordinating conjunctions: și, dar, sau, iar

Romanian coordinating conjunctions join equal parts of a sentence: words, phrases, or complete clauses. Start with și (and), dar (but), sau (or), and iar (and/but with a shift): Ana citește, iar Vlad scrie. (Ana is reading, and Vlad is writing.)

How do you choose a coordinating conjunction?

Choose the conjunction from the relation you want: addition takes și, opposition takes dar, an alternative takes sau, and a linked contrast or change of subject often takes iar. These words do not change form.

How do you use și for addition?

Use și when the second element is simply added to the first. It can join nouns, adjectives, verb phrases, or two clauses: Maria și Paul învață. (Maria and Paul are studying.) Este calm și atent. (He or she is calm and attentive.) Eu gătesc și tu pui masa. (I am cooking and you are setting the table.)

• Between words, și joins items in the same sentence: pâine și brânză (bread and cheese).
• Between clauses, și presents the two events as a straightforward combination: Citesc și ascult muzică. (I read and listen to music.)
• Și can also mean too or also when it adds a participant to an existing idea: Vine și el. (He is coming too.) In this use it is an adverb, not a connector between two full clauses.

How do you use dar for contrast?

Use dar when the second element does not fit the expectation created by the first. It can contrast words or independent clauses: Este mic, dar confortabil. (It is small but comfortable.) Aș veni, dar lucrez. (I would come, but I am working.)

The contrast may be strong or mild. The English translation can still be and in a particular context, but dar tells the listener to notice an opposition: E târziu, dar mai stau puțin. (It is late, but I will stay a little longer.)

How do you use sau for alternatives?

Use sau when the listener is offered two or more possibilities: Vrei apă sau suc? (Do you want water or juice?) It can join words, phrases, or clauses: Mergem pe jos sau luăm autobuzul? (Are we walking or taking the bus?)

• For a simple question, sau is the neutral beginner choice: Ce alegi: ceai sau cafea? (What do you choose: tea or coffee?)
• Ori is also a standard alternative to sau: Vrei ceai ori cafea? (Do you want tea or coffee?) Learn sau first; do not treat ori as an error or as a different basic relation.
• The paired pattern sau...sau can make the alternatives explicit: Sau mergem acum, sau rămânem acasă. (Either we go now, or we stay home.)

Why is iar not always the same as și?

Use iar to link two parts while drawing attention to a change, comparison, or mild contrast. It is especially natural when two clauses have different subjects or actions: Eu pregătesc cafeaua, iar tu aduci cănile. (I am making the coffee, and you are bringing the cups.)

Romanian can use iar even when the contrast is weak and the English translation is simply and: Dan împodobește bradul, iar Maria îl ajută. (Dan is decorating the tree, and Maria is helping him.) If you are only adding two nouns or two equal items, use și: Dan și Maria lucrează. (Dan and Maria are working.)

What changes when you join full clauses?

A conjunction can join two complete clauses without changing the normal order inside either clause. Romanian often omits the subject when the verb makes it clear, so compare Citesc și ascult muzică. (I read and listen to music.) with Eu citesc, iar sora mea ascultă muzică. (I read, while my sister listens to music.) See basic Romanian word order for the clause patterns around these examples.

In short neutral examples, do not put a comma between coordinated words: Ana și Vlad, ceai sau cafea. A comma commonly appears before dar and iar when they join clauses: Vreau să vin, dar nu pot. Eu rămân, iar voi plecați. Short clause coordination with și or sau normally has no comma: Citesc și ascult muzică. Mergem pe jos sau luăm autobuzul? Longer or specially structured sentences can require additional punctuation choices; this article teaches the basic pattern.

Essential variants and related patterns

• Însă is a standard alternative to dar: Vreau să vin, însă nu pot. (I want to come, but I cannot.) It is not a beginner-only or incorrect form.
• Ci is a standard corrective contrast, normally after a negation: Nu beau ceai, ci cafea. (I do not drink tea, but coffee.) Do not replace every dar with ci; for an ordinary contrast, use dar.
• Paired patterns such as și...și (both...and), sau...sau (either...or), and nici...nici (neither...nor) are correlative coordination. With nici...nici, Romanian normally also has nu before the finite verbs: Nici nu beau cafea, nici nu beau ceai. (I drink neither coffee nor tea.) See nici and negative coordination.

Mistakes to avoid

• Do not translate every English and as și. With a clear shift between clauses, iar may be the more natural Romanian choice.
• Do not use ci for an ordinary positive contrast. Use dar: Este scump, dar bun. Use ci for a correction after negation: Nu este scump, ci ieftin.
• Do not put a comma between two coordinated nouns: write Ana și Vlad, not Ana, și Vlad.
• Do not assume și always connects two things. In Vine și el, it means too and adds emphasis to el.
• Do not confuse sau (or) with dar (but): Vrei apă sau suc? offers a choice, while Vreau apă, dar nu este rece. contrasts two ideas.
