Watchful or vigilant
Kreg is a modern phonetic variant of the name Craig, which traditionally stems from a Gaelic word for a rocky crag. However, as a distinct spelling, it is often associated with the Greek name Gregory, meaning watchful or alert. It represents a mid-century American trend of simplifying traditional spellings.
