- Avoid literal translation as 'распаковать' only for files. For relaxation, use 'расслабиться', 'снять напряжение'. Do not use 'декомпрессировать' in everyday psychological contexts.
Common Mistakes
- Using 'decompress' for simple 'rest' (too specific). Confusing with 'depress'. Incorrectly using it as a direct synonym for 'sleep' or 'nap'.
