Honorarium

An honorarium is an ex gratia payment (i.e., a payment made without the giver recognizing himself as having any liability or legal obligation) made to a person for his or her services in a volunteer capacity or for services for which fees are not traditionally required. This is used by groups such as schools or sporting clubs to pay coaches for their costs.^[1][2] Another example includes the payment to guest speakers at a conference to cover their travel, accommodation, or preparation time.
