Morphology

onion + salt

The meaning 'a condiment made from ground dried onion mixed with salt' is directly and transparently derived from combining 'onion' (the vegetable) with 'salt' (the seasoning) in a noun-noun compound denoting a flavored salt. This compositional pattern (ingredient + salt) is common cross-linguistically and would be immediately understandable to a B1 learner who knows both constituents.

Etymology

The compound noun "onion salt" comes from mixing dried onion with salt to make an easy powder you can sprinkle like salt. So, onion salt today means a seasoning powder used 'to flavor' food.
