Translation Traps (for Russian speakers)
- Avoid literal translation like 'скумбриевое небо' which sounds unnatural. The standard equivalent is 'перисто-кучевые облака', but the poetic idiom is lost.
- Do not confuse with 'рябь на воде' (ripple on water) which is a different pattern.
Common Mistakes
- Incorrect: 'mackerel's sky', 'sky of mackerel'. Correct: 'mackerel sky'.
- Using it to describe large, dark rain clouds (cumulonimbus).
- Spelling 'mackeral sky' (missing an 'e').
