glè mhath vs. gu math

[caiptean]

When you want to say (that you're doing) very well, do you just say "glè mhath" or do you say "gu glè mhath"? Do you need the "gu" there? It's my understanding that "math" means good and "gu math" means well, so...? Which is it?

[GunChleoc]

when you use glè you drop the gu - it sort of replaces it.

math - good
gu math - well
glè mhath - very good / very well

[caiptean]

glè mhath tapadh leibh
