The result was redirect to List of medical roots, suffixes and prefixes#G. Out-of-process WP:SNOW close. It seems we're unanimous on the idea that a redirect to the above is a reasonable outcome. Thanks all for quickly chiming in, and thanks to Clarityfiend for finding a good target. Ajpolino (talk) 05:39, 17 February 2021 (UTC)

The article is part dictionary definition and part index of words beginning with "gastro-", both of which are already at English Wikitionary. I don't see sources that discuss the prefix separately, so I don't think it's an independently notable topic. Basically Wikipedia is not a dictionary. Ajpolino (talk) 05:35, 15 February 2021 (UTC)
