lox
LowTechnical (aerospace/chemistry) & Culinary (specialized)
Definition
Meaning
Liquid oxygen; also, a type of smoked salmon.
Primarily refers to liquid oxygen (LOX) in aerospace/industrial contexts. In culinary contexts, it specifically denotes salmon that has been cured in a brine and then cold-smoked (not hot-smoked like kippered salmon). The culinary term is strongly associated with Jewish-American and New York deli culture.

Dialectal Variation
British vs American Usage
Differences
The 'smoked salmon' meaning is far more common in American English, particularly in areas with Jewish deli culture. In British English, 'lox' is understood but less common; 'smoked salmon' is the default term. The 'liquid oxygen' meaning is technical and consistent across both varieties.
Connotations
In the US, 'lox' evokes bagels, cream cheese, and New York delis. It has cultural specificity. In the UK, it's more likely to be perceived as an Americanism or a specific type of smoked salmon.
Frequency
In general American usage, 'lox' is moderately familiar due to the popularity of bagels. In general British usage, familiarity is low for the food term and very low for the technical term outside relevant industries.

LOX is a standard acronym for Liquid OXygen. It is a cryogenic liquid used as a powerful oxidizer in rocket propulsion, welding, and medical applications.
It is pronounced /lɑːks/ (like 'box' but with an 'l'). It rhymes with 'socks' or 'fox'.
No. For the food item, 'smoked salmon' is almost always used. The technical term (LOX) is used in relevant industries but is not part of everyday vocabulary.
