As I suspected, out of a list of 71 words used in English speaking countries that do not have q followed by u, "67 are loanwords from other languages... predominantly Arabic..." Of the remaining words, two are scientific descriptors and the forced QWERTY, which, in my opinion, isn't really a word in the normative, but rather an euphemism adopted for a specific useage. It's neither noun, verb, adverb or adjective...
Also helpful in this discussion is this from English Language and Useage :
"The early Latins had three different letters for the [k] sound: C K Q. However, they only had one letter to represent the [u] and [w] (or [v]) sounds: V. It became customary to write the sequence [kw] (which is fairly common in Latin) as QV and all other instances of [k] as C. (K dropped out of use in most words.) This usage survived into most other European languages that were written with the Latin alphabet, though eventually the letter V was differentiated into U and V, and the accepted spelling of [kw] became QU.
Words spelled with Q without U are generally more recent additions to English, and often represent words borrowed from Semitic languages. Those languages are written with non-Latin alphabets and often have more than one [k]-like sound. When transliterating these scripts, K is usually used for [k], and Q for another sound such as [q], a uvular, "guttural k". In romanizations of Chinese Q is also used for a sound similar to the English "ch"."
