Every month I choose a photograph from Flickr to appear here. Hopefully something interesting and informative or just plain silly.
Imagine trying to tell me how much grass there is in this photo.
The grass in this picture is uncountable. If we wanted to count it we would say "a blade of grass".
So, do you fancy counting all the blades of grass in this picture?
If you see the word "grasses" it means different types of grass.
