Prefixes: sub-, inter-, super-, anti-, auto-
Source: DfE, English Appendix 1: Spelling (2013) — Years 3–4 statutory prefixes
Origins: Latin (sub-, inter-, super-) and Greek (anti-, auto-)
sub- — under, below, less than
Origin: Latin sub (under, below) Purpose: Guide to the prefixes sub-, inter-, super-, anti- and auto- — meanings, etymology, statutory word lists, and morpheme-based practice.
| Word | Meaning |
|---|---|
| submarine | under the sea (sub- + marine) |
| submerge | go under water (sub- + merge) |
| subtitle | text under an image or foreign film |
| subway | an underground passage (sub- + way) |
| subheading | a heading below the main heading |
| substandard | below the expected standard |
| subset | a group within a larger group |
| subtract | take away (sub- + tract = pull away) |
| substitution | something put in place of another |
| subdivision | a division within a division |
Classroom hook: sub- words all involve being underneath or below. A submarine travels under the sea. A subway goes under the road. A subtitle sits under the pictures. Once children know sub- = under, they can decode unfamiliar words.
inter- — between, among
Origin: Latin inter (between, among)
| Word | Meaning |
|---|---|
| interact | act between/with others |
| intercity | between cities (intercity trains) |
| international | between nations |
| interfere | come between; meddle |
| interval | a gap between events |
| interrupt | break in between (inter- + rupt = break) |
| interlink | connect between |
| internet | a network between networks |
| interview | a meeting between people |
| interchange | exchange between two sides |
Etymology note on internet: inter (between) + net (network) = a network connecting other networks. Useful for showing children that even new technology words often use ancient Latin prefixes.
super- — above, beyond, greater than
Origin: Latin super (above, over, beyond)
| Word | Meaning |
|---|---|
| supermarket | a large market (above ordinary) |
| superstar | a person above ordinary star status |
| supernatural | above the natural world |
| superhuman | beyond ordinary human ability |
| superior | above in quality or rank |
| superimpose | place one thing above another |
| supervise | watch over from above (super- + vise = see) |
| superficial | on the surface; above the deep level |
| superpower | a power above ordinary |
| supersede | sit above; replace something |
Classroom hook: super- heroes are above ordinary people. supermarkets are above ordinary markets (in size). Every super- word involves being bigger, better, or above something else.
anti- — against, opposing
Origin: Greek anti (against, opposite)
| Word | Meaning |
|---|---|
| anticlockwise | opposite to the direction of a clock |
| antiseptic | against infection (anti- + septic) |
| antifreeze | against freezing |
| antidote | against poison (anti- + dote = gift) |
| antibody | against foreign bodies in the bloodstream |
| antibiotic | against living organisms (anti- + bio = life) |
| antisocial | against social behaviour |
| anticlimax | the opposite of a climax |
| antivirus | against computer viruses |
| anticipate | act against what's coming; prepare in advance |
Classroom hook: anti- words are always about opposition. An antibiotic fights bacteria. An antidote fights poison. An antihero is the opposite of a hero. Once children know anti- = against, they can make sense of unfamiliar words independently.
auto- — self, by oneself
Origin: Greek autos (self)
| Word | Meaning |
|---|---|
| autobiography | a book about your own life (auto- + bio + graph) |
| autograph | your own signature (auto- + graph = write) |
| automatic | self-operating |
| automobile | a self-moving vehicle (auto- + mobile) |

| autocorrect | self-correcting system |
| autonomy | self-rule (auto- + nomos = law) |
| autocomplete | self-completing |
| autofocus | self-focusing camera lens |
| autodidact | a self-taught person |
Classroom hook: everything auto- does by itself. An automatic door opens by itself. An autobiography is the story of yourself, written by yourself. A car that drives itself would be an autonomous vehicle.
