This article published in the Glendale News-Press summarizes the importance of the placement of prepositions and the intricate list of copular verbs. June Casagrande tells her story of being personally victimized for using the sentence "I feel bad" and ending her sentence with a preposition. Some may argue that the correct form of this sentence would be to say, "I feel badly." June sets the audience straight by informing them that in order to 'express remorse or sympathy, the grammatically correct form is “I feel bad”.
"Copular verbs convey being, seeming or the senses, including taste, feel and smell. Copular verbs don’t express action."
The other criticism she received regarding prepositions being a sign off to a sentence was counteracted by quotes from big time newsleaders.
"Not only is the preposition acceptable at the end, sometimes it is more effective in that spot than anywhere else.” — The Elements of Style
This story seemed to be a defensive mechanism on June's part and all in all this just seemed to be another confirmation that English is the most confusing language ever. And maybe June has some insecurity issues she needs to talk to her doctor about. (Hopefully ending with a preposition didn't offend anyone)
