Definition - A relationship of manner between two lexemes. For example, to nibble is to eat in a certain manner, thus the words nibble and eat have a troponymic relationship.

Etymology -
The term was first proposed by Dr. Christiane Fellbaum of Princeton University in 1990.

Note: As this etymology was gleaned from the Wikipedia, I decided to follow it up and ask Dr. Fellbaum to confirm that she had coined the term. She replied: "Yes, I did coin this term for a lexical-semantic relation in WordNet."
