Word order: freer than English, but not free
Neutral order is SVO, and the rule is theme first, rheme last. Moving a word is an expressive act with a specific effect, not a liberty.
Russian word order is freer than English, and that much of the famous claim is true. What is not true is that it is free. The neutral declarative sentence is subject–verb–object: Я люблю́ му́зыку, Она́ чита́ет кни́гу, Мы е́дем в Москву́. Departures from that order are meaningful and marked. They are not stylistic decoration, and a beginner who shuffles words at random will either sound odd or will change the meaning without noticing. Because case endings identify the subject and the object, the order can move without ambiguity arising — but it moves for reasons.
The reason is communicative. Known information, the theme, comes first; new information, the rheme, comes last and carries the main stress and the ИК-1 fall. Ask Где твоя́ сестра́? and the natural answer is Сестра́ в университе́те — сестра́ is already in the conversation, and the news is where she is. Invert it to В университе́те сестра́ and the emphasis shifts: it is the sister who is at the university, not somebody else. English achieves the same effect only by loading the stress heavily; Russian achieves it by position, and the two normally work together.
One minimal pair shows what reordering actually does. Я люблю́ тебя́ is the plain statement, with the new element at the end. Тебя́ я люблю́ fronts the object and implies a contrast, usually with someone left politely unmentioned — it is you that I love. Люблю́ я тебя́ puts the verb first and the pronoun last, and the effect is warm, colloquial and faintly rueful: the word order of a sigh, a reproach or an affectionate complaint. Three words, three different utterances, and none of them wrong.
Two further facts are genuinely liberating. Inversion is a device with a rule attached, not an accident: putting the predicate or an adverbial first signals news or surprise, so Пришёл Ива́н reports the arrival as the news while Ива́н пришёл takes Ivan as the topic and says something about him. And neither negation nor question formation moves a single word. Adding не leaves the order untouched: Я не люблю́ теа́тр. Turning the sentence into a question also leaves it untouched: Ты люби́шь теа́тр? Only the intonation changes. That is why endings and melody are the two things to get right first; word order is where you start earning expressiveness once they are secure.
