A trend is something that's popular or fashionable right now. Think of it like the latest music style or a new way of dressing.
You see people wearing a certain type of clothing or listening to a particular kind of music, and then you realize that lots of other people are doing the same thing - that's a trend! Maybe you noticed that everyone in school is carrying around an identical phone case. A few months later, those cases are no longer cool, and a new style takes over. That's also a trend. Sometimes trends can be a little annoying, but they're just a way of life for many people who like to follow what's current.
To have a particular direction; to run; to stretch; to tend.
Example: The shore of the sea trends to the southwest.
To cleanse or clean (something, usually wool).
