1) You repay a loan or you pay a loan?
2) What is the difference between stroke and rub?
3) Do you have any words that means pinch but in a more gentle phrase?
5) What are the differences between pebble and gravel and shingle and cobble?
2) So what if I stroke my lover's body and rub her hair?
3) In a more specific context, say, you have a beautiful baby at home and her face is so soft and nice that you want to ____ (same as pinch, any other words?)
4) I did, but I don't know the context. Like, where do you see shingle, cobble, pebble, gravel? I have not the faintest idea. Lexicons are not that long
Cobble = a rounded stone used in the making of a road or pavement, traditionally just big enough to fit into a man's mouth OR a geologic term for a rock or rock fragment with a particle size between 64–256 mm (2.5–10 inches.} This is an image of a cobbled path: Google Image Result for http://easyweb.easynet.co.uk/~iany/patterns/images/cobbled_path.jpg
Pebble = a small, usually rounded, stone
Gravel = a loose mixture of small stones and coarse sand, used for paths and roads.
And beware, since you're in America: "rocks" are much smaller in America than they are over here. In the US, you might call a pebble a rock (and a 'pet-rock' was a handy size - Pet Rock Page). But in Br English a rock is much bigger - weighing at least a kilo, sometimes 100s.
