Questions & Answers about Звонкое эхо возвращается оттуда, откуда вы кричали.
Why do we need both оттуда and откуда when English just says 'from where'?
In Russian, spatial clauses usually pair a demonstrative word in the main clause (оттуда meaning 'from there') with a relative word in the dependent clause (откуда meaning 'from where'). While English often drops the first part and just says 'returns from where', Russian strongly prefers using the full matched pair: 'returns from there, from where'.
Could we use там, где or туда, куда in this sentence instead?
No, because the verb возвращается (returns) describes motion coming away from a source. Там, где indicates a static location (in the place where), and туда, куда indicates a destination (to the place where). Since the echo is coming back from a starting point, you must use the 'from there / from where' pair (оттуда, откуда).
Why does the verb возвращается have the reflexive -ся ending here?
Because the echo is returning itself. The non-reflexive verb возвращать means to return an object to someone, like returning a borrowed book. When the subject is the one physically coming back, you must use the reflexive возвращаться.
Why use the imperfective past tense кричали instead of a perfective verb like крикнули?
