demonstratives

According to the Tibetan phrasebook (particularly handy in the centre of Barcelona) in front of me, Tibetan has not four demonstratives like common or garden languages, but eight. As well as this, that, those and these it also has ya-gi (that up there), ma-gi (that down there), yân-tso (those up there) and mân-tso (those down there). There are perhaps more ways of distinguishing things at different heights on the mountainside (e.g. "Which yak do you mean?") in Tibetan than there are in Dutch, although I have seen stairs and shelves on my few visits to Holland and suspect that most Dutch people don’t live in bungalows.
