Honorarium
（重定向自Honoraria）
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. Another example includes the payment to guest speakers at a conference to cover their travel, accommodation, or preparation time.
