Thankful/Grateful/Appreciative

These words all indicate warm feelings or expressions of gratitude. Grateful and thankful are close in meaning, but one distinction is commonly observed in that grateful is used to describe our feelings of gratitude to another person, and thankful refers to similar feelings towards divine providence, fate, or some less immediate agency. One is grateful for a gift or a kind word, but thankful for good health or fair weather.
Appreciative, more than the other two words, indicates a demonstration of the gratitude a person feels: a secretary who was so appreciative of the opportunity for advancement offered to her that she worked overtime even when not asked to do so.
