If I live to be one hundred years of age, it is my hope that my life will come to exemplify a neologism that is best defined as sumbiotude, or the state of living together. Sumbiotude is the exact opposite of solitude: instead of contemplating life in isolation, sumbiotude involves contemplation and completion of a lifespan with the loving companionship of humans and non-humans.
Albrecht, G.A. (2020) One hundred years of sumbiotude: Resisting the extinction of emotions, The Griffith Review, Getting On: 68, https://www.griffithreview.com/articles/one-hundred-years-of-sumbiotude/
(sumbios = Greek, Living together and the Latin, tūdō, a state or condition)
Use, for example, “the pandemic is bringing sumbiotude out from the solitude as Italians sing to each other from their balconies”.
