Etymology
'proto-gut' is formed from the Greek prefix 'proto-' meaning 'first' (from Greek 'protos') combined with English 'gut' (from Old English 'gutt'/'guttas' or Proto-Germanic *gutt- meaning 'intestine').
The element 'proto-' entered scientific English as a combining form in the 19th century; combined with 'gut' it has been used in biology and paleontology to denote an early or primitive gut structure, yielding the compound 'proto-gut' in modern scientific usage.
Initially the parts conveyed 'first' + 'intestine' in a literal sense; over time 'proto-gut' has been used as a technical term for embryonic or ancestral gut structures and hypotheses about early digestive systems.
