Here's why Lear employed this unusual style:
* Emphasis and Rhythm: The capitalization and separation often highlight key words or phrases, giving them a dramatic emphasis and contributing to the poem's whimsical rhythm. For example, "The Duck" and "The Kangaroo" stand out more prominently.
* Childlike Innocence: This playful use of language mimics the way children often speak or write, emphasizing certain words and phrases for emphasis or dramatic effect. It adds to the childlike and nonsensical tone of Lear's poetry.
* Breaking Conventions: Lear was a master of nonsense poetry. By deliberately breaking grammatical rules and conventions, he creates a sense of absurdity and playfulness, which is at the heart of his humorous verse.
The separation of words, especially prepositions and conjunctions, adds to the quirky, offbeat character of the poem, reinforcing the sense of playful invention.
It's important to remember that Lear's style is not meant to be taken literally or as a grammatical example. It is part of his artistic expression and his unique approach to writing nonsense poetry.
