| 0:00.0 | The Gugu Yemother people speak a language, which is also called Gugu Yomather, that is interesting and valuable in many ways, |
| 0:22.6 | but which is perhaps best known for two main global distinctions. The first is that it is the |
| 0:29.6 | source language for the word kangaroo, which refers to a specific type of kangaroo, |
| 0:34.6 | the eastern gray, which is itself, strangely, a large black type of kangaroo. |
| 0:40.9 | There's a commonly shared myth that the word kangaroo was an aboriginal word for the phrase, |
| 0:46.3 | I don't know. But this, though satisfying and funny, doesn't seem to be true. |
| 0:51.5 | The misunderstanding arose from Captain James Cook and his crew, |
| 0:55.1 | running through a rough word list that had been compiled by a botanist who had visited the area |
| 0:59.9 | 18 years prior, and they were comparing that list with an Aboriginal local on a later visit. |
| 1:05.9 | And the word kangaroo stuck to all kangaroos because of that first documented on paper significance. They pointed at a gray |
| 1:13.4 | kangaroo and assumed that meant all such animals rather than just that one type of animal were kangaroos. |
| 1:20.6 | The other, somewhat famous attribute held by the Gugu Yamathir, language, is its use of of pure geographic positioning rather than egocentric positioning. |
| 1:31.2 | What that means in practice is that rather than saying something is left or right, in front or behind, |
| 1:36.6 | based on the perspective of oneself or potentially another person or location, you give directions based on |
| 1:43.0 | north, south, east, and west. You give absolute |
| 1:46.1 | directions, rather than directions based on a temporal, momentary, or subjective position. |
| 1:53.0 | Just how absolute this rule is within the language has been disputed since the concept was |
| 1:58.4 | first documented and studied, but this doesn't seem to be a |
| 2:01.3 | kangaroo situation. There is something here, and it's not a myth, even if it's not absolute. |
| 2:08.1 | The relevance of this linguistic difference either way is that it shows how subjective most other |
| 2:13.3 | languages that are alive today and those we know something about from the past tend to be in |
| 2:19.5 | terms of placing objects in space. We talk about locations in terms of other locations in terms of |
