locks” vs. “lox

Use "locks" for fastening devices or hair; use "lox" only for brined, smoked salmon served on bagels.

locks

"Locks" is the plural of "lock," a device for fastening doors or securing objects, and also a term for strands or curls of hair ("the locks on the door," "her flowing locks"). It comes from Old English "loc," originally meaning an enclosure or fastening, later extended figuratively to hair, since flowing hair resembles the twisted or bound quality of a fastening.

lox

"Lox" is a noun for brined, smoked salmon, especially the style traditionally served with bagels and cream cheese in Jewish deli cuisine ("a bagel with lox and cream cheese"). It comes from Yiddish "laks," ultimately from a Germanic root meaning simply "salmon," related to German "Lachs."

The real distinction

One word covers fastening devices and hairstyles, the other names a very specific style of cured salmon — a pairing with zero overlap despite the identical sound. "Locks" appears constantly in everyday writing about security, hardware, and hairstyling. "Lox" is a narrower culinary term, most familiar from Jewish deli menus and breakfast spreads, rarely appearing outside food writing. If your sentence involves door hardware, security, or hair, use "locks"; if it involves smoked salmon, especially in a bagel context, use "lox." Because "lox" is such a specialized food term, most writers only encounter the potential confusion when writing about brunch menus or delis. Hardware and security writing relies on "locks" for everything from padlocks to smart locks, while hairstyling writing uses the same word for braided or curled strands. "Lox," by contrast, belongs almost entirely to breakfast and deli menus, rarely straying outside food writing or descriptions of Jewish culinary tradition.

Memory trick

"Locks" ends in the same "-cks" as "clicks," the sound a key makes turning in a fastening device. "Lox" is short and simple like a quick bite of smoked salmon on a bagel — no hidden letters, just a Yiddish loanword for fish.
