trocadores de preposições. No inglês formal, costumamos usar uma preposição mais o pronome relativo
which (como in which, at which ou for which). Embora isso seja gramaticalmente perfeito, pode soar como se você estivesse vestindo um smoking em um churrasco no quintal—um pouco rígido demais para a vida cotidiana.Where substitui in/at which para lugares. When substitui in/on/at which para tempos.Why substitui for which para razões.The gym in which I train is great, mas provavelmente receberá olhares estranhos.

Perguntas frequentes (8)
Yes, in many cases 'that' can replace 'when' in restrictive relative clauses, e.g., 'The day that we met'. However, 'when' is more precise.
No, at a B2 level you should use 'where' for abstract places like 'situations', 'stages', or 'points in a discussion'.
Because 'where' already means 'in which'. Saying 'where... in' is like saying 'in which... in', which is redundant.
It is much less common to omit 'where'. While you can say 'The place I live', it often sounds better to keep 'where'.
'In which' is more formal and used in academic writing. 'Where' is neutral and used in everyday speech.
Yes, but it then becomes a nominal relative clause, e.g., 'Why he left is a mystery.' As a relative adverb, it almost always follows 'reason'.
Yes, but it is archaic. It means 'from where'. You will only see it in old literature or the Bible.
Only if it is a non-defining clause (adding extra info), e.g., 'I live in London, where the weather is often grey.'

donde / cuando
Spanish 'donde' can be used with prepositions like 'en donde', whereas English 'where' usually stands alone.
où
French uses one word ('où') for both place and time, while English distinguishes between 'where' and 'when'.
wo / wann
German relative time markers change based on tense, unlike English 'when'.
Relative clause + noun (no adverb)
Japanese has no equivalent to 'where/when/why' connectors; the word order alone does the work.
haythu / 'indama
Arabic relative clauses often repeat the object/place at the end, which is a major error in English.
...de + noun
Chinese uses a single particle 'de' for all relative relationships, regardless of place, time, or person.
