Hope some of the resident experts in particle physics can respond to it, because I'm unable to find a response to the question:
Is a Goldstone boson the same thing that a Nambu-Goldstone boson?
I suspect that is true because both particles are referred as massless, but I prefer the confirmation of some knowledgeable person

Never mind, I finally found that they are the same thing.
Curious fact: a majoron is a kind of Goldstone Boson
Goldstone bosons have spin 0.

A majoron is a goldstone boson by construction since it comes from the spontaneous breaking of a symmmetry (as any goldstone boson).
