Register: Field, Tenor and Mode
Same topic, different situation, different language
Register is language suited to a type of situation, which Halliday described in three parts: field (what is going on), tenor (who is taking part) and mode (what part language plays).
Ask a Year 7 student to explain photosynthesis to a friend at lunch, then to write it up for a science report, and you get two very different texts. Nothing about the plant has changed; the situation has. Linguists in Michael Halliday’s tradition call language that fits a type of situation a register, and describe the situation in three parts.
Field is what is going on: the activity and its topic, from fixing a bike to analysing a poem. Tenor is who is taking part: their roles, their status and how close they are. Mode is the part language plays: spoken or written, a conversation or a one-way text, a running commentary on an activity or the whole of it. Halliday argued that every clause does three jobs at once, which he called metafunctions: it says something about the world, builds a relationship and organises the message. Each part of the situation mainly shapes one job. Field shapes the content (who does what to whom, where and when), and tenor shapes the relationship (statement or question, how sure or polite we sound). Mode shapes the organisation: what comes first in a sentence (Theme) and how sentences link up.
The link runs both ways. We predict language from situations, and we can rebuild a situation from a few lines of text, which is why we tell a recipe from a complaint at once. Jim Martin later added genre as a separate layer above register, a move still debated. For teachers, the model helps diagnose writing: a weak essay often knows its topic but sounds like speech, with few nominalisations, or is too chatty for its reader.
In actionOne field, two situations
To a friend at lunch: “So basically the plant grabs sunlight and uses it to turn water and air into sugar, yeah?” In a science report: “Photosynthesis converts light energy into chemical energy, which is stored in glucose.”
The field barely changes. Tenor moves from friend to assessor, so basically and yeah? go; mode moves from talk to writing, so the process becomes a technical noun, photosynthesis.
In the classroom
- 1
Give pairs one field, such as a flood in the Mekong Delta, and three situations: a text to a friend, a radio news report and a geography essay. Have them write one sentence for each, then name what changed in tenor and mode.
- 2
Plan every writing task with a field–tenor–mode grid on the board: what the topic is, who the reader is and how close, and whether the text is spoken or written. Learners then choose language to match.
- 3
Build the field before learners draft, as in the teaching–learning cycle: read, talk and make word banks until the topic is familiar, so that drafting effort can go into tenor and mode.
Myth and reality
Register just means formality: formal versus informal language.
Formality is mainly a matter of tenor. Register is the whole configuration of field, tenor and mode, so two equally formal texts, such as a legal contract and a eulogy, belong to very different registers.
Reflect
When a student’s writing “sounds wrong”, is the problem usually field, tenor or mode, and does your feedback tell them which?
Worth a minute before your next lesson, or a conversation in the staffroom.

Halliday, McIntosh and Strevens (1964) first described registers by field, mode and “style” of discourse; later work took up Michael Gregory’s term tenor instead of style. In this 1977 chapter Halliday tied field to experiential, tenor to interpersonal and mode to textual meaning. Halliday and Hasan (1985) gave the best-known teacher-friendly account.
