'customarily-arranged' originates from the combination of 'customarily' and 'arranged', where 'customarily' is derived from 'custom', meaning 'a traditional and widely accepted way of behaving or doing something', and 'arranged' from 'arrange', meaning 'to put in a neat, attractive, or required order'.

'customarily' evolved from the Old French word 'costume', and 'arranged' from the Old French 'arranger', eventually forming the modern English term 'customarily-arranged'.

Initially, 'customarily' meant 'according to custom', and 'arranged' meant 'put in order'. Together, they evolved to mean 'organized in a typical manner'.
