The word “tmesis” is listed as one of “five English words that are utterly unique” in: http://thesaurus.com. It states: “The sole term in the English language to begin with tm- has an unusual meaning to match. Tmesis is the insertion of one or more words between the words that make up a compound phrase. For example: ‘what-so-ever’ inserted in the middle of ‘whatever.’” In Tibetan, the insertion of ma as in the case of ra ma lug (“neither goat nor sheep”) would be a tmesis. There may be other examples.
