topper

The word "topper" moves between a few clear meanings, all connected in some way to the idea of being on top. Most often, it names an item placed on top of something else, either as decoration or as an extra layer. That is why we hear about Christmas tree toppers, cake toppers, and mattress toppers. In each case, the object completes something, improves it, or adds a final touch.

The word also has a regional meaning in education. In Indian English especially, a "topper" is the student who gets the highest marks or ranks first in a class, school, or exam. This sense is common and natural in that variety of English, but it is less common in general British or American English, where people are more likely to say "top student" or "highest scorer."

There is also an older meaning tied to clothing: a "topper" can mean a top hat, especially the tall formal kind linked with earlier fashions. So the word can point to a decorative piece, a useful extra layer, a highest-scoring student in some regions, or an old-fashioned hat. Across these uses, the shared idea is simple: something at the top, whether literally or by rank.
