Core Grammar / Function Words
Joining two things, and setting them against each other. Russian splits “and” and “but” three ways where English has two, and а is the one with no English equivalent at all.
Pure addition. The two halves point the same way and nothing is being contrasted.
Contrast without opposition. It sets two things side by side. English has no single word for it.
Real opposition: the second half defeats the expectation the first half raised.
The everyday “or”, and the options are not necessarily exclusive.
Stronger and more formal. Doubled as ли́бо ... ли́бо it means strictly one or the other.
Another SUBJECT does the same thing. It is about who.
The same subject does an ADDITIONAL thing. It is about what.
Opens a new sentence and adds a further argument. Written register.
The formal но. It can open a sentence, which но normally does not.
A CONSOLING but: the drawback is admitted, then compensated.
Concedes the point and holds the position anyway. Formal.
Colloquial and slightly stubborn: the speaker is holding out.
Introduces the concession, and unlike но it can open the sentence.
Takes the ACCUSATIVE, which is unusual, and attaches to a noun rather than a clause.
Takes the genitive. One thing replaces another.
These comparisons are the reason this page exists. A function word is rarely hard to translate; it is hard to choose.
English uses “and” and “but”; Russian needs three. и adds with no contrast at all: Он ку́пит хлеб и молоко́. а sets two things side by side without either defeating the other: Я чита́ю, а он спит, nobody is thwarted, they are simply different. но means the second half cancels an expectation: Он хоте́л прийти́, но не смог. If you can swap in “whereas”, you want а; if you can swap in “yet”, you want но.
Both translate as “also”, and the test is what is being repeated. то́же repeats the PREDICATE for a new subject: Он врач. Я то́же врач. та́кже adds a new predicate to the same subject: Он врач, а та́кже писа́тель. A useful shortcut: то́же answers “who else?” and та́кже answers “what else?”.
All three contrast, with different attitudes. но is neutral. зато́ is consoling: it concedes a drawback and then offers compensation, so Кварти́ра ма́ленькая, зато́ в це́нтре is optimistic where Кварти́ра ма́ленькая, но в це́нтре is merely factual. одна́ко is the formal register, and it is the one of the three that can comfortably begin a sentence.
