Syntax: "A-bless my soul" uses the prefix "a-" before a verb, which is an informal, dialectal, or archaic construction adding emphasis. "What's a-wrong with me?" follows the same pattern with "a-wrong." The phrase "like a man on a fuzzy tree" is a simile introduced by "like," comparing the narrator's itching to an unusual situation.
Morphology: "Itchin'" is a phonetic spelling representing the informal pronunciation of "itching," dropping the final 'g'. This is common in colloquial speech and song lyrics to reflect natural pronunciation.

Syntax: The structure uses parallel clauses with "and" to connect symptoms: "my hands are shaky" and "my knees are weak." "I can't seem to stand on my own 2 feet" uses the modal verb "can't" (cannot) with the infinitive "to stand." "2 feet" is a stylized spelling of "two feet."
Morphology: "Shaky" is an adjective derived from the verb "shake" with the suffix '-y,' meaning 'tending to shake.' "Weak" is the base adjective form. "Can't" is a contraction of "cannot."

Syntax: This is an imperative sentence starting with "Please don't ask me..." followed by a wh-clause "what's on my mind" (what is on my mind). The second sentence is a compound sentence joined by the coordinating conjunction "but," contrasting being 'shook up' with feeling 'fine.'
Morphology: "Don't" is the contraction of "do not." "What's" is the contraction of "what is." "Shook" is the past participle of 'shake' used here as an adjective in the colloquial phrase 'shook up.'

Syntax: "When she touch my hand" uses the present subjunctive or a colloquial form where the third person singular verb 'touches' loses the '-es.' "What a chill I got" is an exclamatory clause. "Her lips are like a volcano that's hot" is a simile using "like" to make a comparison, with a relative clause "that's hot" describing the volcano.
Morphology: "Touch" is used instead of the grammatically standard "touches," reflecting informal or dialectal speech. "That's" is a contraction of "that is." "Hot" is the base adjective.
