A again works as the prefix meaning with and D again is third. PU works into PUGO, meaning as unto; PUIM, meaning sharp or sickles; PURGEL, meaning fire. The N then is again, the Lord of Hosts. Lord and Fire are obvious equivalents; so we can take PUN together as a variant on the root of PURGEL. The idea of sharp in PU gives us the idea of it being a strong fire. AD then works together to be a variant on the prefix.
