Definition
Meaning
The plural form of 'onion', referring to the edible bulb of a plant from the genus Allium, characterized by a strong smell and pungent taste, commonly used as a vegetable or flavouring in cooking.
Can refer metaphorically to layers of complexity (peeling back the layers of an onion), or in slang (especially in sports like American football) to mean a particularly tough or formidable opponent.
Linguistics
Semantic Notes
Primarily a countable noun in plural form when referring to multiple individual bulbs. Can be used as an uncountable noun when referring to the substance or ingredient (e.g., 'Add some onion'). The singular form 'onion' is used for the plant species, a single bulb, or the ingredient concept.
