'in-kind' originates from the phrase 'in kind,' where 'kind' meant 'type' or 'nature' in Old English.

'in kind' was used in Middle English to denote something of the same type or nature, eventually evolving into the modern usage of 'in-kind' to describe non-monetary transactions.

Initially, it meant 'of the same type or nature,' but over time it evolved into its current meaning of 'provided in goods or services rather than money.'
