Learning
Memory Aids
Mnemonic
Think of a train DE-RAIL-ing: it comes OFF the RAILS. For the metaphor, imagine a plan 'coming off the rails' of its intended track.
Conceptual Metaphor
PROGRESS/PLANS ARE A JOURNEY ON RAILS; DISRUPTION/F AILURE IS COMING OFF THE RAILS.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'крушение' which is broader (shipwreck, collapse). 'Derailment' is specifically about leaving tracks. For the metaphor, 'срыв' or 'провал' might be closer.
Common Mistakes
- Using 'derailment' for minor delays (too strong). Confusing with 'train crash' (a derailment may not involve a collision).
