We have to state why the following sentences are not gramatical:

a) Robin forced the sheriff go
(I know there should be a "to" before the go, but I don't get the "rule" of why its gramatically incorrect)
f) He came a large sum of money
g) Did in a corner little Jack Horner sit?
h) Elizabeth is resembled by Charles.
k) It is eager to love a kitten
l) That birds can fly amazes.
n) Has the nuse slept the baby yet?
O) I was surprised for you to get married.
p) I wonder who and Mary went swimming.
q) Myself bit John.
S) What did Alice eat the toadstool and?

In sentence a) you need the "to" because "to go" is a necessary infinitive in this construction. Check out infinitives in this site.

f) He came INTO a large sum of money.
The way the sentence reads originally, "sum" is placed as a direct object. A preposition is needed to clarify the sentence.

g) The adverbial prepositional phrase, "in a corner," modifies sit -- so should be placed at the end of the sentence.

These explanations should get you started. If you post your answers to the rest of the sentences, we'll be glad to give you feedback.

To determine why these sentences are not grammatically correct, we can identify the specific grammar rules that are violated. Let's go through each sentence:

a) Robin forced the sheriff go.
This sentence is missing the word "to" after the verb "forced." The correct sentence should be: Robin forced the sheriff to go.

f) He came a large sum of money.
This sentence is missing the preposition "into" or "with" to indicate how he received the money. The correct sentence should be: He came into a large sum of money or He came with a large sum of money.

g) Did in a corner little Jack Horner sit?
This sentence is inverting the subject and the verb in a question format. The correct sentence should be: Did little Jack Horner sit in a corner?

h) Elizabeth is resembled by Charles.
The sentence is using the incorrect form of the verb "resemble." The correct sentence should be: Elizabeth is being resembled by Charles or Elizabeth is being resembled by Charles.

k) It is eager to love a kitten.
This sentence doesn't violate any grammar rules but it might be considered awkward or unusual. A more common sentence could be: It is eager to have a kitten or It eagerly loves kittens.

l) That birds can fly amazes.
The sentence is missing the subject before the verb "amazes." The correct sentence should be: The fact that birds can fly amazes.

n) Has the nuse slept the baby yet?
This sentence contains an incorrect word order. The correct sentence should be: Has the nurse slept with the baby yet?

O) I was surprised for you to get married.
This sentence is using the incorrect preposition. The correct sentence should be: I was surprised by you getting married or I was surprised when you got married.

p) I wonder who and Mary went swimming.
This sentence violates grammar rules by not using proper sentence structure. The correct sentence should be: I wonder who went swimming with Mary.

q) Myself bit John.
This sentence is using the wrong pronoun. The correct sentence should be: I bit John.
Note: The reflexive pronoun "myself" should only be used when the subject and the object refer to the same person.

S) What did Alice eat the toadstool and?
This sentence is missing the word "did" before "Alice." The correct sentence should be: What did Alice eat, the toadstool and?

By identifying the specific errors in each sentence, we can learn the grammar rules that govern the correct usage of the language.
