'resource-focused' originates from the combination of 'resource' and 'focused', where 'resource' refers to a stock or supply of materials, and 'focused' means concentrated on a particular point or task.

'Resource' comes from the Old French 'resourse', and 'focused' is derived from the Latin 'focus', meaning 'hearth' or 'fireplace'.

Initially, 'resource' referred to a means of supplying a need, and 'focused' meant concentrated. Together, they evolved to mean concentrating on the efficient use of resources.
