Informal language is characterised by features that operate across all five subsystems — phonology, morphology, lexicology, syntax and discourse — as well as through specific forms including colloquial language, slang, taboo language, dysphemism, swearing, and digital elements like emoticons and emojis.
The five subsystems describe the different structural levels of language. In informal texts, each subsystem shows distinctive patterns:
| Subsystem | Informal Features |
|---|---|
| Phonology | Elision (gonna), assimilation (lemme), g-dropping (talkin’), reduced vowels |
| Morphology | Clipping (arvo, brekky, servo), diminutives (doggo, prezzies), blends (brunch) |
| Lexicology | Colloquialisms, slang, taboo vocabulary, hyperbole, neologisms |
| Syntax | Ellipsis, minor sentences, left-dislocation, parataxis, reduced structures |
| Discourse | Backchannels, turn-taking features, non-fluency, adjacency pairs, narrative structure |
KEY TAKEAWAY: Strong analysis identifies features at multiple subsystem levels, not just vocabulary. A single informal text can exhibit phonological reduction, morphological clipping, colloquial lexis, syntactic ellipsis and discourse-level backchannels — each reinforcing the informal register.
Colloquial language is everyday informal vocabulary used in casual conversation — it is not necessarily slang (which is more specialised and in-group specific), but it belongs firmly to informal registers.
Australian colloquialisms include:
- Clipped forms: arvo (afternoon), servo (service station), footy (football), brekky (breakfast)
- -ie/-y suffixes: postie, tradie, journo, pollie
- Informal intensifiers: heaps, dead set, massive, legit
- Discourse markers: like, you know, sort of, kind of
Colloquial language signals in-group solidarity, reduces social distance and reflects the distinctive character of Australian English.
Slang is highly informal vocabulary that is typically group-specific, rapidly changing and carries strong social connotations. It functions primarily to:
- Signal in-group membership (only insiders know the term)
- Express attitude and identity
- Maintain linguistic freshness through innovation
Examples range from occupational slang (dog for an informant in criminal slang), youth slang (slay, no cap, bussin), sports slang and regional slang.
EXAM TIP: When you discuss slang, always explain its social function — who uses it, who is included by it, and who is excluded. Slang is not just colourful vocabulary; it is a mechanism for creating and policing group boundaries.
Taboo language refers to words and topics that violate social norms — typically involving sex, bodily functions, death, religion or illegal activities. What counts as taboo is culturally and contextually variable.
Dysphemism is the use of a harsh, blunt or offensive term where a neutral or euphemistic one might be expected:
- snuffed it instead of passed away
- shrink instead of psychiatrist
- bog instead of toilet
Dysphemism can signal: irreverence, dark humour, in-group bonding, rebellion against social norms, or emotional honesty.
COMMON MISTAKE: Students sometimes describe taboo language as simply rude or inappropriate. In analysis, explain its pragmatic function: taboo language can establish solidarity, mark in-group membership, release tension or challenge social hierarchies.
Swearing (profanity, expletives) is a special category of taboo language with strong phonological and emotional properties. Research (Timothy Jay, Robin Lakoff) suggests swearing functions to:
In Australian English, expletives often undergo semantic bleaching — losing their offensive force through repeated use — and can become general intensifiers or discourse markers (bloody good, f*ing hell as surprise).
In digital informal texts, visual elements substitute for prosodic and paralinguistic features:
| Element | Function | Example |
|---|---|---|
| Emoticons | Express emotion via punctuation | :-) :-( ;-) |
| Emojis | Rich visual expression of emotion, tone, concept | 😂 🤦♀️ 💀 |
| Context-specific graphemes | Symbols with group-specific meaning | 💅 (done, fabulous), 💀 (dying of laughter) |
| Elongation | Conveys prosodic stress or emotion | noooo, soooo good |
These features compensate for the absence of intonation, volume and facial expression in written communication.
APPLICATION: When analysing digital informal texts, treat emojis and elongation as prosodic substitutes. Ask: what would the speaker’s voice be doing at this moment if this were spoken? Then explain how the digital feature recreates that effect in writing.
VCAA FOCUS: VCAA examiners expect you to use precise metalanguage when discussing these features. Avoid vague descriptions like “the writer uses casual language.” Instead: “The morphological clipping ‘arvo’ and the informal intensifier ‘heaps’ contribute to the colloquial register, signalling solidarity between the interlocutors.”
