# isogram

noun (an isogram, isograms)

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

## Everyday

1. An isogram is a word in which no letter appears more than once, such as «dog», «planet» or «uncopyrightable». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#m1)
2. (geography) An isogram is also a line on a map joining places that have the same value, such as the same temperature or height; isotherms and contour lines are kinds of isograms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#m2)

### In the lessons

In word puzzles, spelling games and olympiad problems pupils check whether a word repeats a letter; in geography it names lines on weather and height maps. Phrases: «is it an isogram?», «the longest isogram».

### Examples

- «Lamp» is an isogram because no letter repeats. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#x1)
