# ir

fragment (ir-, prefix; IR, abbreviation)

«ir» in the English dictionary: everyday and in Jewish tradition — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

1. «Ir-» is a prefix meaning «not», used before words beginning with «r», as in irregular (not regular), irresponsible (not responsible) and irrelevant (not relevant). [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#m1)
2. «IR» is a short form for infrared, light just beyond red that we cannot see but feel as heat, used in TV remote controls. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#m2)
3. «Ir» is the chemical symbol for the element iridium. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#m3)
4. (Irish, Scots, slang) In some written dialect, «ir» may stand for «our» or «are». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#m4)

### In the lessons

In spelling lessons, «ir-» explains the double r in words like «irregular» and «irresistible»: ir + regular. In science lessons, IR (infrared) cameras see heat and remote controls send IR signals. It is not a word on its own in standard English.

### Examples

- «Irregular» means «not regular»; the «ir-» means not. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x1)
- The TV remote sends an IR signal to the television. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x2)
- An IR camera can show warm animals at night. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x3)
- Add «ir-» to «responsible» to make «irresponsible». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x4)
- «Ir» is the symbol for iridium on the periodic table. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x5)
- Irrelevant means not connected to the topic. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/ir/#x6)

### Note

Not an English word on its own. As a prefix it doubles the «r»: ir + rational = irrational. Other «not» prefixes: un-, in-, im- (before m, p, b), il- (before l). «IR» in capitals is an abbreviation.
