Thinium
Thinium , vel duna, in geographia physica est collis arenosa a rationibus ventorum factus; a vento pedetemptim thinia moventur. Thinia variis formis et magnitudine inveniuntur. Pleraque sunt latere ventoso latiora, quam ubi harena adversus clivum impellitur. Campus thiniorum est regio a permultis thiniis operta.

Thinia desertorum magnorum, quae aream immensam operiunt, saepe voce Casachica barchan nominantur.
