i would like to know what is the difference between those words.
in order to make things easier, may i use always UNDER?
pls someone help me carify my doubt.
When you are referring to direction, these prepositions are usually interchangeable.
The subway runs under/beneath/below/underneath the street. You can usually use under in those situations.
Sometimes, when these words are used idiomatically, you have to use the exact word from the idiom.
His actions are beneath contempt.
I am working under a new management team.
Below implies relative position.
The bumper of the car is below the roof, however, it is not underneath it.
Underneath implies close relation to the object above.
Beneath implies that the object is completely overshadowed by the object above, as does underneath and to a lesser extent, under.
Below and under are less specific terms.
The pea was underneath the blanket. (You have to lift the object above to find the pea.)
Below decks - the huge space on a ship that is below the level of the main deck, even if there is no part of the main deck above that space.
Underneath the Sarcophagus they found the Canopic jar.
(You need to remove the Sarcophagus to get the jar.)
The Canopic jar was found under the Sarcophagus.
(You might have needed to move the Sarcophagus, but not necessarily.)
I hope that makes it slightly clearer, though the subtleties are often not noticed by the average reader.
