Words about words

You fix, mend or repair something if it is broken and doesn't work. Fixing it will make it work again, or make it look as good as new. Not everything that is broken can be fixed.

Something is flammable if it is possible to set it on fire. Some things are more flammable than others, and a larger surface area tends to make things more flammable. For example, dry grass is highly flammable but large pieces of wood won't catch fire easily.

A flash is a bright light that you only see for a very, very short time. When you take a photo with a camera in dim light you usually use a flash to light the objects in the photo up so you will be able to see them.
A flash can also be used to describe something you only see for a very short time, or didn't quite see clearly, as in "I saw the rabbit flash by".

Something is flecked if it has small spots of another color through it. Many different kinds of stone are flecked, and the iris of many people's eyes are flecked.

Something is flexible if it can be easily bent into new shapes. Garden hoses are made of flexible plastic. The man in the picture is very flexible, and is a contortionist.

lan You flip something when you quickly turn it over, either half-way over so it is upside down or flipped over all the way so it comes back to where it was to start with. The boy in the picture is doing a backflip.

Flitting means to move quickly from one place to another, the way a small bird flits between branches.

Something flows if it moves in a smooth, continuous way, like the flow of water down a river.

A fluid material is one that can flow and is easy to change the shape of. Liquids and gases are fluid.

You fold something when you bend it over itself neatly. The man in the picture is folding clothes. Folded clothes are neater and take up much less room in the cupboard than unfolded clothes. They will be less wrinkly when you take them out, too.
