every other

every other

1. All except for some previously mentioned set.

   Two of the bolts were loose, but every other bolt I checked was fine.

2. Every second; each alternate; the second of each pair in turn (perhaps used because "every second" could also refer to "second" as a unit of time or be interpreted as meaning "only the second").

   Every other person in the line wore a pink bowtie.

   Although I work from home, I visit the office for a meeting every other day.
