IPA: /əˈpriːʃiətəri/
KK: /əˈpriːʃiətɔːri/
Showing gratitude or recognition for something positive or valuable.
She gave an appreciatory nod after receiving the compliment.
Appreciatory is formed from "appreciate" (from Latin "appretiare", meaning to value or estimate) and the suffix "-ory" (meaning relating to or characterized by). The word "appreciatory" refers to something that expresses or conveys appreciation or gratitude.
Think of valuing something ('appreciate') and how the suffix '-ory' relates to that action — so, appreciating is about expressing gratitude.
