I want to learn how easy the verb APPEAR lends itself to the usage of itself with a participle. For example,
His speech appeared worrying.
What you wrote at first appeared worrying—but it probably must not be.
The above ones are OK, I think. Would these work?
Marvel appeared reading the book.
Lucy appeared going somewhere.
Sahar appeared going home.
Appear, like seem, look, sound, feel, can be followed by an adjectival complement, but not an -ing clause.
They can sometimes be followed by a noun phrase, but only in certain cases, eg look a mess, seem a nice man, but not look a melon or seem a car.
If you ask why these restrictions apply, I'm afraid that the whole of the answer is "Because that's how Modern English is".
