From Dianna Wynne Jones' A Tough Guide to Fantasyland -

Few NAMES in Fantasyland are considered complete unless they are interrupted by an apostrophe somewhere in the middle (as in Gna’ash). The only names usually exempt from apostrophes, apart from those of most WIZARDS, heroes, and COMPANIONS on the Tour, are those of some COUNTRIES. No one knows the reasons for this. Nor does anyone really know how an apostrophe should be pronounced, though there are theories:
1. You ignore the apostrophe and simply pronounce the word. (Here Gna’ash = Gnash.)
2. You leave a gap or lacuna where the apostrophe occurs. (Here Gna’ash = Gna-ash.)
3. You make a kind of clucking-sound to stand for the apostrophe. (Here Gna’ash = gnaglunkash.) Persons with insecurely mounted tonsils should adhere to one of the other two theories.
