The Spanish traer, meaning “to bring,” comes from the Latin trahere, meaning “to drag.”
From the Latin root, we also get a few related English words that aren’t obvious at first glance:
- Tractor: What is a tractor if not a machine that brings or drags machinery around the plot of farmland?
- Traction: What is traction if not something moving so quickly that it drags everyone else up along with it?
Note that the -h- vanished when the Latin turned into Spanish but became a -ct- when the Latin became English. Thus the t-r-[nothing] of traer maps to the t-r-ct of the English words.
