Curumo (Saruman) - Igwiša3ûlêz (white crafter) - Igwiš (“white”); A3ûlêz (“crafter”, as Saruman was more into machines, being a Maia of Aulë, both Valarin)
Aiwendil (Radagast) - Âyawin-gimabâz (bird-finder) - Aiwē-n(d)il (“small bird-lover”, Primitive Quenya); gimba- (“find”, Black Speech, almost corresponding in function to “-ndil”, in that Radagast seeks to see and be with the birds and wildlife of Aþâraphelûn)

Pallando or Rómen(s)táro - Barâdâz-âyanâz (east/raised-helper) - Barâdâz (“raised”, used for “east”, as this is from where the Sun has been “raised” into the sky, Neo-Valarin from Primitive QuendiBaradá “lofty, sublime”); ayanûz (“Ainu”, used for “worker”, as the Ainur worked to create and sustain the universe, Eä, Valarin)
“The ‘other two’ came much earlier, at the same time probably as Glorfindel, when matters became very dangerous in the Second Age. Glorfindel was sent to aid Elrond and was (though not yet said) preeminent in the war in Eriador.
But the other two Istari were sent for a different purpose. Morinehtar [Alatar] and Rómestámo [Pallando]. Darkness-slayer and East-helper. Their task was to circumvent Sauron: to bring help to the few tribes of Men that had rebelled from Melkor-worship, to stir up rebellion… and after [Sauron’s] first fall to search out his hiding (in which they failed) and to cause [dissension and disarray] among the dark East.
They must have had very great influence on the history of the Second Age and Third Age in weakening and disarraying the forces of East… who would both in the Second Age and Third Age otherwise have… outnumbered the West.”
