Under

0 1. I guess you could use both, but better options would be under/beneath. Below doesn't have the sense of immediately underneath (the letter was on the floor below the bed). 02br
02br
02br
002. Depends. It is feasible, but it would be an unusual railway line that exactly follows the line of the river and the road, which is the meaning of along. Over means that

00I think both are correct. What is your opinioN? 02br

00JT: I'd say no to 'below', Hanuman. My feeling is that 'below' connotes more permanent or longer duration event, while 'under' denotes a shorter time event. 02br

0 I would agree with Nona: 'under the pillow', 'over the river and road'. 02br

00'Below' suggests 'lower than'; I suggest that we would so rarely say that 'something' was 'below' a pillow, that it can be more or less discounted as a possibility. 'Under her pillow' is the correct idiom. 02br

00Similarly, I can conceive of circumstances in which a

0 Similarly, I can conceive of circumstances in which a railway line would run along a road, for a while; but I think 'over' is the more usual option. As for the river – when someone invents a hydrorail, maybe. It would certainly be surprising if a railway line managed to run along both. 02br

00JT: In North America, both roads and railway lines often parallel a river fo

0 Well, I'd probably use 'run by/alongside/beside' in those situations. With 'run along', I get a distinct impression of wet wheels; perhaps because a train 'runs along' a track. 02br
02br
00But if people elsewhere would say 'run along the river', in such circumstances, fair enough. 02br

0 The best explanation I have heard of the difference between "under" and "below", which I posted recently in a different thread, says that "under" means "in a lower position within a vertical stack," while "below" means "on a lower horizontal plane." If the two items are in contact, they occupy the same horizontal plane, so "below" does not work. However, things do not always have to be touch

0 I don't think duration really has much to do with it, although it seems to in your example. Maybe "the plane flew under the clouds" means that for a moment the plane happened to be directly under a cloud, while "the plane flew below the clouds" means that the cloud level was at 3,000 feet and the plane flew at 2,000 feet. 02br

0 Furthermore, we wouldn't say "she kept it below her pillow" either. 02br

00I don't understand the vertical stack/horizontal plane distinction - it seems to me that it is below that rather suggests some kind of closer connection in a vertical way - as in the example provided. 02br

00Can't we say "in the area below that" when pointing at a chart

00According to the vertical stack/horizontal plane distinction that we are considering, all of the B's are below the A, but only the C's are under the A. I think in this case I would consider another possibility - "direc
