a preliminary and medial series in words of Latin beginning, as with quarrel, quarrel, quadrant, query, etc.
An initial series in some words of Anglo-Saxon (or other Teutonic) beginning, precisely written kw-, or as originally cw-, but modified at the center English period to qu- in conformity because of the spelling of French and Latin terms with qu- (see 1). It occurs in quail, quake, qualm, queen, quell, quick, etc. It will not happen medially except in structure.
An initial series in some Middle English or modern-day dialectal (Scotch) variations of terms on a regular basis spelled with wh-, as with qual, qwaylle, quhal, for whale; quhilk for whilk (which), quhyp for whip, etc.
a preliminary series of various beginning except that the above mentioned, as in charming, quassia, quay, quince, quip, quire, quire, quiver, quoin, quoit, etc. start to see the etymology of these terms.
