- It is not related to 'green onions' or 'spring onions' (зелёный лук).
Common Mistakes
- Confusing it with edible sea vegetables like samphire or seaweed.
- Using it as a general term for any onion grown near the sea.
- Incorrect pluralisation: 'sea onions' (acceptable but rare, referring to multiple plants) vs. 'sea onion' (usually uncountable for the species).
