Questions & Answers about Вчера РФ подписала договор.
Why does the verb подписала have a feminine ending if РФ ends in a consonant?
РФ is an initialism standing for Российская Федерация (the Russian Federation). To determine the grammatical gender of an indeclinable acronym or initialism, you look at its head noun. Since Федерация is a feminine noun, РФ takes the feminine verb agreement подписала.
How is the abbreviation РФ pronounced out loud?
You pronounce it using the Russian names of the letters: эр-эф. Note that the spoken stress falls on the final letter.
Does РФ decline in other cases?
No, РФ is completely indeclinable. Whether it acts as the subject like in this sentence, or is used in another case like в РФ for the prepositional, the form remains exactly the same. Initialisms generally only decline if they are read as a smooth word rather than letter-by-letter and happen to end in a consonant.
I have heard native speakers pronounce договор with the stress on the first syllable. Which is correct?
The strict literary stress is on the final syllable: догово́р. While you will frequently hear native speakers say до́говор in everyday colloquial speech or business jargon, it is generally considered non-standard. At the B2 level and in formal contexts, it is safest to stick to догово́р.
