Haplology

MORPHOLOGY: process by which a segment or a sequence of segments is deleted if it immediately precedes or follows the same segment or sequence of segments. EXAMPLE: the English possessive 's is not pronounced after the plural morpheme -s (e.g. John's reaction vs. the two cats' reactions). In Dutch, the noun-forming suffix -eling may attach to nouns, verbs and adjectives (dorpeling 'villager', zuigeling 'infant', stommeling 'idiot'). If the base ends in the sequence -el, one of the -el-sequences is haplologically deleted (edel 'noble', edeling 'nobleman').
