on nodding terms
1
used when a relationship is limited to simple greetings
Its origin can be traced back to the social customs of the 18th century. In those times, it was customary for people of the upper classes to greet each other with a bow or a nod instead of shaking hands. The nodding gesture was a sign of recognition and acknowledgement, but it was not necessarily a sign of familiarity or friendship. Therefore, if two people were on nodding terms, it meant that they knew each other and acknowledged each other's presence but were not necessarily close friends or associates.
- Despite their faded friendship, Emily and Alex remained on nodding terms, acknowledging each other with a friendly nod whenever they crossed paths.
- John and Mary are on nodding terms.They say hello to each other when they see each other, but they don't really know each other.
