Explanation:

A poem with the free occurrence of sound without any restrictions of regular or formal meter and rhyme scheme. It is the literary style that is free from constraints that help the poet to shape to poem according to his desires. It includes natural rhythm and avoids artificial restrictions. However, there are uses some literary devices like rhyme, rhythm, alliteration that the poets feel necessary and that would enhance the impact of the poem but irregularly and informally. This device allows the poets to write with complete liberty without concerning about the meter which leads to the creation of a natural art piece.

1. can be neither seen nor touched:  abstract noun

Abstract nouns name things that are not concrete or that we can not detect with either of our five senses like theories, feelings, emotions, conditions, qualities, intangible concepts and events like death, birthdays and marriages.

2. has a receiver named: transitive verb

Transitive verbs are those verbs that in order to express action and be complete, they need an object or a receiver of that action like “buy,” “send,” and “take.” For example, “I sent a letter yesterday” In this sentence, “sent” is a transitive verb because it needs a receiver in order to express a complete action.

3. has no receiver named: intransitive verb

Intransitive verbs are those verbs that can express action without having an object or receiver of that action, like “read” in the sentence “I read all day long” and “wait” in the sentence “I will wait until 8 o'clock”

4. expresses highest or lowest degree of comparison: superlative degree

Superlative degree adjectives are those used to compare three or more things, animals, persons or actions and express the highest or lowest degree of comparison. Take a look at the following examples (superlative degree adjectives underlined):

Vanessa Grant is the tallest model of Bolivar city.

I think William is the most brilliant student in our school.

5. add sign of possession to last name:  joint ownership

Add the sign of the possessive to the last name: Joint ownership

To express joint ownership about something (when two or more nouns own the same thing), we can indicate it by adding an apostrophe to the last noun (name) that posses the "thing". For example, Taylor and Amy's laptop (Both Taylor and Amy own the laptop).

6. indicates time: verb tense

Verb tenses indicate the different types of past, present and future.

7. -ly : adverb suffix

There are many types of adverbs, some of them are formed adding the “-ly” suffix to an adjective like in the words happily, quickly, carefully and daily.

8. modifies a noun: adjective

Adjectives modify, describe or give us more information about nouns. For example, in the sentence “the yellow flowers withered faster than the rest,” the word “yellow” is an adjective because it describes the noun “flowers.”
