The story of Aj

AJ is a name made from two initials. As a nickname it has long been used for boys whose first and middle names begin with A and J, and some families now register it as the name itself. There is no single meaning behind it, so what it stands for depends on the family.

AJ first appears in the CSO records in 2011, and for a few years only a handful of boys a year were registered with it.

It picked up from 2020 onwards. Its best year was 2022, with 25 boys, and in 2025 it reached number 210 once the spellings are combined. The CSO records each way of writing it separately: Aj had 22 boys in 2025, while A J and A.J. appear in some earlier years.
