What´s the difference between adverbs and prepositions if the words are the same?
399387
Prepositional phrases can function as an adverbial such as the case with:\n My brother works in an insurance company.\n                   or \nTo my suprise, the doctor phoned the next morning.\n\nI think you looking for prepositional adverbs. \n\n This is an adverb which behaves like a preposition with the complement omitted. \n\n A car drove past the gate. (past=a preposition)\n\nA car drove past. (past=a prepositional adverb)\n\nHope this is what you were looking for.

Unnecessary Prepositions\nIn everyday speech, we fall into some bad habits, using prepositions where they are not necessary. It would be a good idea to eliminate these words altogether, but we must be especially careful not to use them in formal, academic prose.\n\nShe met (up with) the new coach in the hallway. \nThe book fell off (of) the desk. \nHe threw the book out (of) the window. \nShe wouldn't let the cat inside (of) the house. [or use "in"] \nWhere did they go (to)? \nPut the lamp in back of the couch. [use "behind" instead] \nWhere is your college (at)? \nall words in parenthesis are unnecessary

It is a question of style\n\nThe use of the definite article "the" gives more emphasis on the prepositional phrases.\n\nconsider\n\n"it prevents elimination"\n\nand "it prevents the elimination" (of what?)\n\nprepositional phrases function much the same was as an adjective, they modify a noun in this sentence.  By emphasizing the noun with "the" you emphasize the prepositional phrases, relative clauses, and adjectives that go along with it.\n\nuse of "the" also emphasizes that the words assimilation and elimination are nouns and not verbs.\n\nIf you are descibing a process such as digestion, I would not use "the", because you have more emphasis on the process, a verb.  If you are describing the effects of a drug or the results of an experiment, the emphasis is no longer on how something happend but on what happend.  I would use "the" in this case.

There is no difference. In this context both sentences have the same meaning, though "Playing tennis is fun" is probably more acceptable.

The simple predicate is "finished."  \n\nHere is the whole sentence:\n\nThe  men finished the game in    a   short time.\nadj  sub verb     adj d.o. prep adj  adj   obj of prep

"Into" is a preposition, so yes.\n\nA prepositional phrase is one that can be removed from a sentence, leaving a still-sensible sentence behind.  \n\nExample:\n\nThey went (into the bedroom) to make the bed.\nThey went to make the bed.\n\nWhoops, sorry, I completely read "prepositional" and not "propositional" phrase.  Then again, it would normally be called a "proposition," not propopsitional phrase...

The verb of a sentence states what the subject does. \n   For example: "The dog ran down the street." The dog is the subject and the verb "ran" is stating what the subject does.

clauses contain subjects and verbs whereas phrases don't.  adjectives modify nouns.  adverbs modify verbs, adjectives or other adverbs.  an infinitive is a non-conjugated verb (to run, to walk, to eat).  sorry i can't answer about an apositive or gerund.

English is very subtle and prepositions are very tricky.  You could also have said "I am disappointed by the news" if that had been offered as an alternative.\n\nI think that it is "at" in this case because you are confronting the news and you don't like what you see.\n\nIf you are disappointed "with" something, it means that you were expecting better and received something not up to expectations.  "I am disappointed with my results."  "I am disappointed with my present."\n\nIf you are disappointed about something, it means that you are not quite so intimately involved with it.  "I am disappointed about the way in which the government is running this country."\n\nIf you say you are disappointed in someone, then you feel let down by that person.  "I am disappointed in you, Harry.  I expected better of you!"\n\nKeep reading good books in English and note the uses of prepositions.  They are very tricky indeed and even native speakers have to stop and think sometimes!

This would be a lot of work to explain.  Each series of words, while they could be considered the same in meaning [up to a point], really don't mean the same.  Some are very different, some less different.  Sometimes it is a question of degree, sometimes it is a question of emphasis, and sometimes it is a question of not at all the same.\n\nFor example, "because of" strictly means "was caused by."  It is very active and direct.  The others in the series could be substituted for because of, but they don't really mean the same: owing or due to means a situation owes its existence to the existence of another thing, as a result of means more that a situation is something that develops out of another situation.\n\nThis particular series shows that people will vary their language without being overly particular as to the exact, specific meaning of the phrases they use.\n\nlearn means to acquire knowledge or skill.  know means to have a grasp in the mind of something, to see something clearly for what it is.  recognize means to grasp that something seen has been seen before.  release means to let go of.\n\nIn English, nouns can be formed from adjectives and verbs, but not adverbs, even though it might at times appear that they do.  This is a case of "changing form class."  Red is a word that can be a noun or an adjective.   Cut can be a noun, verb, or adjective [Cut the cake.  I have a cut on my finger.  Send her some cut flowers.]\n\nLearning English is a lot harder than people who grow up speaking it realize.  It must be very puzzling to people who grew up speaking some other language.  But every language has its difficulties.

There NEVER was a rule against splitting infinitives. Years ago, somebody thought that because Latin infinitives can't be split (because they are a single word), that English infinitives can't be split. Some how this ridiculous idea caught on, and some teachers took up the cause.\n\nIt is not a rule. Never was a rule. Put the adverb wherever it will be most effective without adding ambiguity.\n\nCan you imagine this sentence without the split infinitive:\nYou can expect to more than double your earnings.

Based on what you're saying, it sounds like you are talking about a preposition.  For example, "under the chair," "beside the couch," and "near the table" are all prepositional phrases.  They deal with the relationship of something to something else.  (Under, beside and near are the prepositions in those sentences -- I think the chair, couch and table are the objects of the preposition).

Adverb, a word that describes an action:\n\nHe ran QUICKLY\nShe walks too SLOWLY\n\nIntejection, a word that just sort of expressed an emotion that doesn't really mean anything:\n\nUGH, that's horrible.\nWOW, those are great.\n\nPronoun, a word used in place of a noun:\n\nThe bar looks nice, IT is very modern looking\nWho's that girl, SHE looks very nice\n\nAdjective, a word that describes an object:\n\nThe ball is YELLOW\nShe drank her COLD beer
