[Terechu]

Esa palabra ye nueva pa mi. Yo hubiera usao maña, pero nun da pa to'los matices. Va a haber que traducila de maneres distintes, según el contextu: maña, arte, empeñu, porque nun hay equivalente plenu.

That's a new word for me. I would probably have used maña, but that would not cover it's full scope. It probably needs different translations depending on the context: i.e. skill, craft, artfulness, resolve..., because there's no full equivalent.
