In normal English syntax, single-word modifiers precede the noun they modify, but phrases follow the noun.
So you put the -ing word before the noun it modifies when it is acting as an adjective, not as a non-finite verb. You put the -ing word after the noun when it is part of a verbal phrase with other parts in it; you can’t have a long verbal phrase preceding the noun it modifies.
Sometimes the -ing word is actually a noun: a writing desk is a desk for writing, not a desk that happens to be writing. But it is still modifying desk. Here are examples of the -ing word used as a modifier (either as adjective or a noun) preceding the modified noun:
answering machine, barking mad, bleeding heart, bowling alley, burning
bush, burrowing owl, carrying capacity, changing room, chattering classes,
closing credits, coloring book, cooking oil, creeping thyme, dictating
machine, drawing board, drilling rig, eating disorder, fighting drunk,
firing squad, floating bridge, flying fish, flying buttress, flying fox,
flying fuck, growing pains, heating element, holding pen, hopping mad,
killing field, landing gear, laughing gas, lending library, lightning bug,
magnifying glass, mailing list, missing person, moving walkway, opening
night, parking meter, plunging neckline, praying mantis, quaking aspen,
revolving door, rising sun, rounding error, scalding hot, shifting use,
shouting match, starting line, talking point, thinking cap, trading post,
waiting game
On the other hand, here are pairs of examples where the first one has the -ing word first where it acts as a simple adjectival modifer, and where the second one has it acting as an actual verb:
- the acting director had harsh words for us
- the director acting in the company’s best interests keeps a tight ship
- the binding action of this substance
- the cord binding the two halves together
- the bouncing ball hit me in the face
- the ball bouncing down the stairs was lost forever
- the calling function retains its own private variables
- the woman calling for a new husband will soon enough find one
- the carrying case was very heavy
- the case carrying the lead was heaviest of all
- the circling vultures drifted ever higher
- the vultures circling above our heads would wait until we dropped
- the cooking sausages smelled fabulous
- the women cooking our breakfast made us wash up first
- a demanding teacher is hard on the students
- a teacher demanding full attendance is seldom listened to
- the facing audience recoiled
- the man facing the audience cheered
And so on and so forth. In your case, you could have put sleeping afterwards, and had a man sleeping under the tree, but sleeping men like sleeping dogs are not particularly unusual.
However, you would not normally speak of fishing men, so you would have a man (who was/is) fishing for something down by the river bank. If you strained it, you could build up a context in which fishing men might contrast with farming men or some such, but it would be abnormal.
You might find a man singing in the rain, or you might find a singing man (who is out) in the rain, but you will never find a singing-in-the-rain man. Or to put it more crudely, there is a world of difference between having a fucking idiot in your livingroom and having an idiot fucking in your livingroom.
Your description of the use of the definite article as opposed to the indefinite article is accurate. The presence or absence of one of these articles, however, in no way alters that standard usage.
As for why the article may disappear, it strikes me that when the article is there, it draws attention towards the adjective and away from the person. Let me use sentences 4 and 5 to illustrate:
It seemed Walter didn't pay any attention to a tearful Kitty.
Stated this way, the sentence indicates that Walter is not paying attention to Kitty's tearfulness; he is not moved or affected by her distress.
She hasn't got lovely eyelashes like marvelous Monica.
In this case, the attention of the sentence is squarely on Monica, and "marvelous" is relegated to being a pure adjective, neither calling for nor receiving any unusual or special notice from the speaker. If we added "the," it would put the attention on the fact that Monica is marvelous. (This can, by the way, be a vehicle for sarcasm, if you want to point out that she's really not all that marvelous after all.)
Best Answer
The Original Poster's explanation is fairly accurate. Here is a more in depth account:
Agents and patients
In the sentence:
Bob is the person doing the action. In grammar, we say that Bob is the AGENT of the punching action. Me, the person receiving the punches, I'm the PATIENT. I am the recipient of the punching action. Now look at this sentence:
The grammar of this sentence is different, but Bob is still the agent, and I am still the patient of this sentence. Bob is doing the action. The action is being done to me.
Adjectives
Now, some adjectives explain how nouns do things, sometimes to other people or things. Here are some examples:
Notice that in these examples the music has the effect of annoying people. The story has the property of interesting people. The water has the property of giving life to other things. These -ING adjectives describe potential actions:
The nouns that these adjectives describe, are the potential AGENTS of the actions. In the phrase
.. the word music describes the agent of the annoying action. ING-adjectives usually describe the AGENTS of the potential action.
However, adjectives ending in -ED are different! This is because ED-adjectives normally describe the PATIENTS of actions.
In the sentences above, the students didn't bore anybody. Something or somebody bored them. They were the recipients of a boring people action. Similarly, something excited the monkeys. The monkeys didn't excite anybody. In the last sentence, something annoyed the customers. They did not annoy somebody else.
Conclusion
ING adjectives describe the AGENTS of actions. But ED ones describe the PATIENTS of actions. Annoyed habit is wrong, because nothing annoyed the habit! Habits don't have feelings, so it is very difficult to annoy habits! In the same way, "news" doesn't have feelings. We can't excite the news! Of course the news can excite people and habits can annoy people. For this reason, exciting news and annoying habits would be correct.
In other words, the Original Poster is correct.
This is frightenING:
This is frightenED
