The word "Boxen" is an intriguingly spelled word that isn't commonly used in English. The spelling can be explained through IPA phonetic transcription as /ˈbɑksən/. This unusual spelling is a result of adding the -en suffix to the noun "box." In German, the -en suffix is commonly used to indicate the plural form of a noun. While it's not a grammatically correct English pluralization, "Boxen" has been used to describe multiple boxes, particularly in the context of technology or computing.
Made of boxwood; repeating the points of the compass in any order; in the wrong box, mistaken.; box of a coach, the driver's seat on a carriage.
