Grammar Notes, Vocabulary.

1. My surname is Simpson.

This sentence is correct, the noun phrase "my surname" directly relates to Simpson. The same applies to "My car is blue". Quite correct, but as we will see further down the page, not applicable to adjectival confusions.

2. Because I woke up at five in the morning, I feel weary.

Correct - "feel weary", weary, being an adjective modifies feel, which is a noun in this sentence. "I am weary" would also be correct.

3. Feelings are very abstract things.

Again, correct, "abstract" as an adjective modifies things, the object of the sentence.

4. Atomic bomb can liquidate many people.

This sentence, is incorrect for two reasons.

A. "Atomic bomb" is a singular subject. Singular subjects MUST take an article "An atomic bomb can liquidate many people".

B. This sentence COULD be correct if atomic bomb were plural. "Atomic bombs can liquidate many people", would be a correct sentence. A plural subject does not require the article.

5.Getting an A++++++++++++++++++++++in her test, so and so was hysteria.

This sentence is also incorrect.

Hysteria is a noun, that's like saying "so and so was chair" The adjective form "hysterical", which would have also been acceptable, would have correctly modified the noun "so and so".

Grade of 3/5

Please be careful when modifying sentences.

1. Many nouns ALSO have adjectival forms.

2. A singular subject MUST take an article "a/an/the".
