Mnemonic
Think: DE- (undoing) + COMPENSATION (making up for a deficit) = the undoing of previous adaptation, leading to failure.
Conceptual Metaphor
SYSTEM FAILURE UNDER PRESSURE (like a dam breaking after holding back water).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'декомпенсация' in non-medical contexts; it's a false friend in general language.
- Do not confuse with 'decompression' (разгерметизация/снижение давления).
Common Mistakes
- Using it as a general synonym for 'decompression'.
- Using it in non-technical contexts where 'breakdown' or 'failure' would be clearer.
