Talk:thematical

This appears to be used in "European English" by non-native speakers, creating it as the obvious back form from "thematically". As a Wiktionary novice, is there a way that I can indicate this under Etymology, and that the preferred word would normally be "thematic"? It doesn't appear in most of the Oxford printed dictionaries, for example. --Petrolmaps (talk) 08:28, 9 September 2020 (UTC)
