Cultures Where Men and Women Don’t Speak the Same Language
For example, in the following cultures, men and women really do speak different languages (at least some of the time).
Chukchi
Chukchi is an endangered language spoken by 5,000 people in East Siberia. Traditionally, the Chukchi herd reindeer and hunt for seals and whales.
The Chukchi language is made up of two gender-based dialects, one for men and one for women. The differences between the two dialects are mostly phonetic. For example, women typically substitute the ts sound for ch and r. So “ramkichhin,” which means “people,” is pronounced as written by men and as “tsamkitstsin” by women.
At the same time, the differences aren’t quite as simple as just swapping one consonant for another, which is why scholars refer to Chukchi as having two separate, but still mutually intelligible, gender dialects [PDF].
