-eme

This suffix is a term that was developed in the study of linguistics. OED defines it as follows:

'in Linguistics the termination of many names of significant or distinctive units of structure of some kind in the lexicon, grammar, and phonology of languages, e.g. grapheme, lexeme, morpheme, phoneme, semanteme, toneme.' (See the entries for these words, in this Guide or in the OED - or any good dictionary - for a fuller explanation of their meanings.)

To my current knowledge, only one important word outside the field of Linguistics has been coined with this suffix. This is the word meme.
