Mnemonic
Think of the SUN making you say 'RAY!' because its beams are so bright. Or, a STINGRAY has a long, flat body that could look like a wide ray of light underwater.
Conceptual Metaphor
HOPE/GOODNESS IS LIGHT; thus, 'ray of hope' maps a positive emotion onto a physical beam.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'рей' (rei) meaning 'line/row' in contexts like очередь. The fish 'ray' is 'скат'.
- The phrase 'луч света' is a direct equivalent for 'ray of light'.
- 'X-ray' is 'рентген', not a direct translation of 'ray'.
Common Mistakes
- Incorrect article: 'He is ray of hope.' (Correct: 'He is *a* ray of hope.')
- Confusing spelling: 'rey' (incorrect).
- Using 'ray' for a non-linear spread: 'The light ray covered the whole room.' (Better: 'The light *filled* the room.')
