Attestations from sources in English: 

to use something to make something else
"As for technology, the term that best encapsulates the way I am think- ing about it is the action-noun tlachichihualiztli (tla [something] + chichihua [to adorn, dress, embellish] + liztli [the being or doing of something]), which roughly translates to 'something one uses to make something else.' Tlachichihualiztli emphasizes a process of ongoing creation and innovation. Contributors to these processes are referred to in the Nahuatl language with distinct descriptors based on areas of expertise and contexts."
