The Tebe-Tebe River originates in the mountainous areas in the East of the country and joins the much bigger Phuthiatsana River, which in turn empties into the majestic Mohokare River. The Mohokare forms one of the longest borders between Lesotho and South Africa in the West. The nearest small town called Teyateyaneng (popularly known as T.Y.) may have got its name from this river. It seems that another smaller river, not too far from Tebetebe, called Tejajejane got its name from the river Tebe-tebe. The name Teja-tejana is the simplification of the word Tebe-tebe to give an impression that it is the smaller form of the bigger river. The town, T.Y borders this river and gets its name from it.

According to the locals, the name of the town used to be called Tejatejaneng (a place of the river Tejatejane). However, the inhabitants claim that during the colonial period, the British colonialists who presided over the country then, could hardly pronounce the word Tejatejaneng, instead, preferring to call it Teyateyaneng (indeed a letter ‘y’ hardly appears in the local language), which is now abbreviated to T.Y (or “Tioae” as the locals commonly indigenise the name). This small district town has implications for the proposed Biopark as it is about 20 minutes drive from Ha ‘Mamathe and has a good accommodation for visitors who may be unable to stay overnight in the park.
