A tribute is a thing said, done or given as a mark of respect or affection. Followed by 'to' it's an indication of a praiseworthy quality (as an example, my dictionary gives 'their success is a tribute to their perseverance' which I particularly like). A tribute used to be how miners pay was calculated and could also mean a payment made by one state or ruler to another.
Tribute is also the make of our van (or do I mean model?)
Don't forget #writingchat tonight. The theme is 'what do you write?' and 'why?'
