We tried lots of languages (Greek, Spanish, Cherokee, you name it!) and even looked at cocktails (hint from Gimlet Media)...but nothing felt right...at the end we figured it needs to be something super simple but also tied into other aspects of what we're doing...
Since most of our users are traveling, we thought about things you see while traveling (animals, famous places, etc) as well as the actions you take (packing, moving, flying, etc)...in the end we loved the idea of "pack" -- it can be a noun, verb, whatever you want...but it was obviously taken across social media...
So we played around with Pak, Pakk, Pacq, Paqk, etc. We settled on Pak & Paq then ran it by some friends--good thing!!!--as apparently Pak is a racist slur for Pakistanis (never knew that)...so we went with Paq which fits into "have you Paq-ed for your trip?" "drop a Paq" and our mascot...Ally the Alpaqa!
Another tip is to think about what your core demographic is and play to those languages/strengths...While we loved "caja" (spanish for box) in Hebrew (we're based in Tel Aviv) it sounds like "cacha" which means "so-so"
Hope this helps!
