The suffix -dom

English suffixes such as -ly and -est (friendly, quickly, fastest, strongest) are very common. In contrast, the suffix -dom occurs in few words. Here's a list of common words with -dom:

boredom
fandom
filmdom
freedom
kingdom
martyrdom
stardom
wisdom

Less common than kingdom is queendom. The suffix -dom combines with either a noun or an adjective. This is illustrated by the following:

boredom A + Af
fandom N + Af
filmdom N + Af
freedom A + Af
kingdom N + Af
martyrdom N + Af
stardom N + Af
wisdom A + Af

The structure of boredom is bored + dom and of wisdom it is wise + dom. Af corresponds to affix.

The suffix -dom also occurs in words which have more common equivalents. For example, the words Christendom, consumerdom and sisterdom are less common than Christianity, consumerism and sisterhood.

The suffix -dom is far less productive than other English suffixes. It can combine with both nouns and adjectives. It can derive nouns from adjectives such as freedom and is thus classified as a derivational affix.
