Question

the root greg means group. what does the word egregious mean?
untrustworthy or worthy of suspicion
standing out from the rest in a particularly bad way
said in a wordy and confusing way

Explanation:

The prefix "e-" (a variant of "ex-") means "out of", and the root "greg" means "group". So "egregious" literally means "out of the group", and its modern definition refers to something standing out negatively from others.

Answer:

standing out from the rest in a particularly bad way
