"Under" and "from below" are two terms used in different situations. The big confusion when writing is because these words have the same sound.
So, check here the main rules, uses and examples about each of these words.
Under
The word “underneath”, written together, is an adverb of place meaning that something is located at the bottom in relation to something else.
So it is synonymous with below, below, below, inside; and antonym of above or above. Most of the time, this adverb is accompanied by a proposition thus forming an adverbial phrase: underneath.
Examples:
John was under of the viaduct waiting for the rain to pass.
the keys were under of the pillow.
I found a cockroach under of the mat.
the beggar lives under from the bridge.
I found your hat under of the bag.
Note: Generally the term “under” can be replaced by the preposition “under”. That way, you can substitute it in the sentence to confirm that the term you are using is the correct one. So, if the sentence is consistent, the term used is correct.
Example: The keys were under the pillow. (under the pillow)
Under
When written separately, this term plays the role of an adjective in a way that qualifies the noun in the sentence. The word “from below” is formed by the preposition “from” plus the adjective “low”.
Examples:
our conversation was under level.
I think Tarcisio is a man under character.
The entire interview was permeated by words under slang.
When I arrived at the meeting, Carolina looked under above.
Our apartment is on the floor under.
Note: A tip is to replace the word with “under” and if the sentence doesn't make sense, the correct term is “under”.
