Inversion in poetry
CHARTLESS
I never saw a moor,
I never saw the sea;
Yet now I know how the heather looks,
And what a wave must be.
I never spoke with God,
Nor visited in Heaven;
Yet certain am I of the spot
As if the chart were given.
(Emily Dickinson. 1830–1886)

2. DETACHMENT

It is a kind of inversion when, as a rule, an adverbial modifier or attribute is syntactically isolated from the words it refers to. Detachment is usually shown by commas, dashes, or brackets.

Detachment Very small and child-like, he never looked more than fourteen. Elegant, weary, infinitely fragile, Mrs. Glamber lay back in her armchair listening.

3. PARENTHESIS

Parenthesis is a variety of detachment. These are explanatory or qualifying words, clauses, or sentences inserted into a passage with which it doesn't necessarily have any grammatical connection, and from which it is usually marked off by round or square brackets, dashes, or commas.
Some phrases are very often used in the parenthesis, like I guess, I suppose, maybe, perhaps, probably, and etc.

Parenthesis John will come tomorrow, I’m sure. They didn’t see – none could see – her distress, not even her grandfather.

4. ELLIPSIS

Ellipsis is an omission of one or more words in the sentence. It is typical of spoken colloquial English.

Ellipsis – Were they interesting books? – Don’t know. Haven’t read them. Looked pretty hopeless. Early evening. April. Perhaps, perhaps not.
