Language & Style
Explore register, rhetorical devices, tone and mood, and learn to analyse how language shapes meaning in speeches and texts.
Register: Formal vs Informal
Register refers to the level of formality in language. Writers and speakers adjust their register depending on their audience, purpose, and context.
Formal Register
- Complete sentences, correct grammar
- Sophisticated vocabulary
- No slang or contractions
- Third person, passive voice common
EXAMPLE
"It is with great regret that we must inform you of the cancellation of the scheduled event."
Informal Register
- Casual, conversational tone
- Contractions (can't, won't, I'm)
- Slang, colloquialisms allowed
- First/second person, active voice
EXAMPLE
"Hey, sorry but the event's been called off. Total bummer!"
Rhetorical Devices
Rhetorical devices are techniques writers and speakers use to persuade, emphasise, and engage their audience.
Anaphora
The repetition of a word or phrase at the beginning of successive clauses or sentences. It creates rhythm and emphasis.
EXAMPLE
"We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields." — Winston Churchill
Tricolon (Rule of Three)
A series of three parallel words, phrases, or clauses. Groups of three feel complete and memorable.
EXAMPLE
"Government of the people, by the people, for the people." — Abraham Lincoln
Hyperbole
Deliberate exaggeration for emphasis or effect. Not meant to be taken literally.
EXAMPLE
"I've told you a million times not to exaggerate!"
Antithesis
Placing two contrasting ideas side by side in a balanced structure to highlight their difference.
EXAMPLE
"That's one small step for man, one giant leap for mankind." — Neil Armstrong
Tone and Mood
Tone
The writer's or speaker's attitude towards their subject or audience. Tone is conveyed through word choice, sentence structure, and rhetorical devices.
Examples: sarcastic, earnest, authoritative, pleading, celebratory, solemn.
Mood
The emotional atmosphere a text creates for the reader or audience. Mood is what the audience feels.
Examples: hopeful, tense, melancholic, inspiring, uneasy, triumphant.
Key Distinction: Tone is about the writer; mood is about the reader. A writer's sarcastic tone might create an uncomfortable mood for the audience.
Analysing a Famous Speech
Martin Luther King Jr., "I Have a Dream" (1963) — an excerpt.
Excerpt from "I Have a Dream"
I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal."
I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.
I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
Analysis
Anaphora
The phrase "I have a dream" is repeated at the start of each paragraph. This anaphora creates a rhythmic, almost musical quality and drives home King's central vision with increasing emotional power.
Antithesis
King contrasts "the sons of former slaves and the sons of former slave owners" sitting together — an antithesis that highlights the gulf between past injustice and his dream of reconciliation.
Tone and Mood
King's tone is earnest, passionate, and prophetic. The mood it creates is deeply hopeful and inspiring, urging the audience to believe in the possibility of change.
Personal Appeal
By referencing "my four little children," King shifts from the political to the deeply personal. This makes his argument emotionally compelling and universal — every parent can relate to wanting a better future for their children.

Worked Examples
Identify the rhetorical device.
"Education is the most powerful weapon which you can use to change the world." — Nelson Mandela
Device: Hyperbole / Metaphor.
Analysis: Calling education a "weapon" is a metaphor — it compares education to something that has physical power. Describing it as "the most powerful" is hyperbolic emphasis. The effect is to elevate education as the ultimate tool for social change.
Describe the tone and mood.
"The streets were empty. The windows were dark. Somewhere, a dog barked once and was silent."
Tone: Detached, observational — the writer reports what they see without commentary.
Mood: Eerie and tense. The short, declarative sentences and details of emptiness and silence create an atmosphere of unease. The single bark that stops abruptly heightens the feeling that something is wrong.
Switch the register.
Informal: "Honestly, I reckon the school rules are way too strict — like, nobody even follows half of them."
Formal version: "It is my considered opinion that the school's regulations are excessively restrictive. Furthermore, a significant proportion of students do not consistently adhere to them."
What changed: Slang ("reckon," "way too," "like") was replaced with formal vocabulary. Contractions were expanded. The first person was softened with a formal hedge ("it is my considered opinion").
