I preferentially use the ancient Greek ‘sumbios’ for a family of new concepts I am developing. The term ‘symbiosis’ is a New Latin and German construction of the scientific community in Germany around the late 1800s (although some identify its first use from around 1622). According to the Concise Oxford Dictionary, the modern term ‘symbiosis’ has its origins in the Greek sumbiosis ‘a living together’, from sumbioun ‘live together’, from sumbios ‘companion’ or ‘living together’. In order to focus on the social/cultural context of the science of symbiosis, I have used the social origins of ‘sumbios’ to distinguish its applications from bioscientific use. Hence, the neologism ‘sumbiotude’ has its origins in the Greek sumbios and the Latin tūdō, a state or condition. As opposed to solitude, sumbiotude means to enjoy a state of companionship with others.
