**** Usage notes
Both [en] and _last name_ are extremely common terms for family names in all
dialects of English. The former is somewhat more common in the UK and the
latter in the US. Because of the cultural or gendered associations involved,
however, it is increasingly common to prefer [en] or [en] in multicultural or
official contexts.
