'fun-centered' originates from the English word 'fun' combined with 'centered', where 'fun' meant 'enjoyment or amusement' and 'centered' meant 'focused on'.

'Fun' and 'centered' have been used in English since the 17th century, and the combination 'fun-centered' emerged in modern English to describe activities or events focused on enjoyment.

Initially, 'fun' meant 'light-hearted enjoyment', and 'centered' meant 'focused on a central point'. The combination 'fun-centered' has retained this meaning.
