'explicitly-provided' originates from the combination of 'explicitly' and 'provided', where 'explicitly' means 'clearly' and 'provided' means 'supplied'.

'Explicitly' and 'provided' have been used in English since the 16th century, and their combination into 'explicitly-provided' is a modern usage to emphasize clarity in provision.

Initially, 'explicitly' and 'provided' were used separately, but their combination emphasizes the clarity and specificity of provision.
