'customizable' originates from the verb 'customize', which is derived from 'custom', meaning 'a traditional and widely accepted way of behaving or doing something'.

'custom' evolved from the Latin word 'consuetudo', which transformed into the Old French 'costume', eventually becoming the modern English word 'custom'.

Initially, 'custom' referred to 'habit or tradition', but over time, it evolved to include the idea of 'modifying or adapting something to suit personal preferences'.
