wordplay - A rhyming riddle

My little sister came up with this riddle:

Preposition, adverb, and suffix too,
It relates in every situation to you.

Veggies of the ground or fruit of a brood,
Drop the first letter of the scrumptious food.

A master of writing and founder of fear,
Whose works are always lurking near.

The seeing spots on the face of a bird,
Is an epithet for the shortened word.

The word is important in farms or magazines,

It means what it says and says what it means.

I'll give it some time and if no one has solved it, I'll get her to write a hint.

Good luck!

Answer

Okay, I am certain I have the answer, but I'm having trouble making some of the clues fit.

The answer is

onomatopoeia

Preposition, adverb, and suffix too,
It relates in every situation to you.

"on" is a preposition, adverb, and suffix. Not sure about the second line.

Veggies of the ground or fruit of a brood,
Drop the first letter of the scrumptious food.

"Tomato" is the answer to the first line. Drop the "t" and you get "omato"

A master of writing and founder of fear,
Whose works are always lurking near.

Who else but Edgar Allen "Poe"?

The seeing spots on the face of a bird,
Is an epithet for the shortened word.

Iowa is considered a "flyover" state, and someone flying over it would have a "bird's eye" view of it. The abbreviation for Iowa is "IA".

The word is important in farms or magazines,
It means what it says and says what it means.

This stanza is a reference to onomatopoeia as a whole. Farm animal noises are described using onomatopoeia ("Pig goes oink, cow goes moo"), and the second line is basically a straight definition of onomatopoeia! Not sure about magazines, though, unless it's a reference to gun magazines and sounds like "Bang!"

The clues I'm not sure about are "It relates in every situation to you", "fruit of a brood", "Whose works are always lurking near", and "magazines".

Any help on filling in blanks would be appreciated, but I would be shocked if this isn't the answer.
