_Lanà_ is a very useful word, and often serves as a sacred anchor, which beginners, slightly acquainted with the language, catch hold of to make themselves understood. It means that which is the instrument, means, or part of performing any thing. This shall be elucidated by examples. The Abipones constantly chew tobacco leaves mixed with salt, and the saliva of old women, calling it medicine. They come at all hours, and say, _Tach kaûe Paỳ npeetèk yoetà_: Father, give me tobacco leaves, my medicine. Having obtained this, they presently add, _Tach kaûe achibiřaik noetà lanà_,: Give me also salt, which serves to compose this medicine. Another comes and says: _Tachkaûe latařan lpahè lanà_: Give me a knife to cut my meat with, or _Tachkaûe këëpe yëëriki lanà_: Give me an axe to build my house with. Persons better acquainted with the language generally abstain from the use of this word _lanà_, in place of which they make noun substantives of verbs, by which the instrument or means of doing a thing is admirably expressed. Thus, _Noetarèn_, I am healed. _Noetarenátařanřát_, medicine. _Noetaranatařankatè_, a medical instrument. _Hakiriogran_, I plough. _Kiriogrankatè_, a plough. _Ñahategřan_, I shear. _Ahategkatè_, scissars, or snuffers, which, as it were, shear the wick. _Géhayà_, I behold. _Geharlatè_, a looking-glass. _Rietachà_, I fear. _Netachkatřanřat_, an instrument of terror. They facetiously call remarkably ugly faces by this name as if they were a terror to the eyes. _Latè_, indicates the place of action, thus: _Nahamátřalatè_, the place of the fight. _Kiñieřalatè_, the place where one eats, that is, the table.
