In the books there are tons of clues regarding the ethimology of many names but it can be kind hard to catch/remember them all so maybe collecting all those we find in a post could be useful and interesting for everyone.
I'll post the ones i found (and i hope more will come for you

Obviously there will be some spoilers so new readers watch out.
-Kellanved
In TCG faint refers to Atri-ceda Aranict as Kellan Varad (high mage).
Any clue about what ved could mean? could it be somehow connected to Veed?(he comes from 7c, where 1st empire language is spoken)
Curious thing is, the emeperor came from Dal Hon so it's kind of strange to find a 1st empire word in his name.
-Brys
In the same scene faint asks for water saying "berys"... not exactly the same word but remeber they speak in "high diction". Particularly interesting if you consider how Brys found himself inside Denaeth Rusen(hope the spelling is correct).
-T'orrud Segul
"Shield anvil" So segulehs are "the anvil" and in darujihstan we have the "shield cabal"
- the T'
LOTS of names/words start with a T'.. we learn in Moi (i think) that this means broken. ??so could t'orrud be a broken /deviated attack??
-Nom
Nom means "knife" in Imass language... how the Nom family actually came to have an imass name is unknown
-Tiste Andii
A lot of andii have the word "and" in their name(anomANDer nenANDa ANDarist nimANDer sANDalath ), wich arguably could mean "darkness or something similar. This leads to suppose their names are composed by words... such supposition is also enforced by the fact that the word "Dragnipur" appears in anomander's second name
-T'lan imass
T'lan is a contraction of Tellan, and also shows the T' .. possibly indicating that the imass lives were broken in the ritual.
A lot of imass names are explained in the book
Onos is "clanless man"
Ool is "veined"
Lan is "flint"
Aral Fayle is a short version of "Chen're aval lich'fayle" =touched by the stone
Nom Kala is "knife drip"
-Mael
"bloodmane" in edur language, referring to the red seafoam after a sacrifice.
-Iskar jarak
"bird who steals", a title curiously used also by the moranth in Gotm
also it appears that our dear Pust got "bird" in the name.
-Mhybe (sigh) or "Mahybe"
apparently "a vessel".
Used as honorific for a mother among barbaric populations.
Also a clay vessel for one's soul among the nomadic populations of kolanse.
