### In the lessons

It is an honest entry for an abbreviation, not a word. Children see «ct» on jewellery («18 ct gold»), on addresses, in hospital talk («a CT scan») and on maps and letters in the USA. In maths, «ct» on a price label means cents. Phrases: «18 ct gold», «a CT scan».

### Examples

- Mum's ring is 18 ct gold. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x1)
- The diamond weighs 2 ct. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x2)
- We live at 4 Maple Ct. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x3)
- The doctor sent Grandad for a CT scan of his head. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x4)
- My penpal lives in Hartford, CT. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x5)
- The sticker said 99 ct. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/ct/#x6)

### Note

Not a word you say aloud: read it as «carat», «cent», «court», «C-T scan» or «Connecticut» depending on the place. Trap: «carat» (gem weight), «karat» (gold purity, US spelling) and «carrot» (vegetable) sound the same. In maths, 24-carat gold is pure; 18-carat gold is 18/24 = three quarters gold.
