### meaning for a pupil

1) An isogram is a word in which no letter appears more than once, such as «dog», «planet» or «uncopyrightable». [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#m1)

### sense 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://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#x1)
- «Letter» is not an isogram, because it has two t's and two e's. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/isogram/#x2)

Countable. Say «EYE-so-gram». «Iso» means equal and «gram» means something written or drawn. Check carefully: capital letters count the same as small ones.

### In the corpora

- ["Uncopyrightable" has 15 letters and not one of them repeats; a word with no repeated letters is called an isogram.](https://md.mova.elamur.ai/free/en/corpora/school/language/36-grammar-puzzles-part-two/13/)
