In the sentence "the trees uneasily frowned on....", I was wondering if saying "the trees hauntingly frowned on....." is synonymous. From the look of the definitions of the words "uneasily" and "hauntingly" they seem to be synonymous in this context, however I'm notentirely sure whether that is true.
These two constructions do not communicate the same thing to me, although it is hard to pinpoint why. Here is why they seem different:
In "the trees uneasily frowned on...", you seem to be characterizing the trees' frowning as inducing anxiety in them (the trees).
In "the trees hauntingly frowned on...," you seem to characterizing the trees' frowning as inducing anxiety in some other party (e.g. the narrator or protagonist).
This is probably because of the difference between uneasy (an adjective, not derived from a verb and thus never associated with a direct object) and haunting (which derives from the verb to haunt which does take a direct object).
No, they are not synonymous. "Uneasy" is a quality of comfort (lack of). "Haughty" is a quality of attitude, a kind of unfriendliness, a purposeful way of projecting disapproval (believed superiority).
But besides that, the quote is very difficult to decipher (or paraphrase) because it's a strange anthropomorphizing of trees.
