I have several ways of directing my creativity.
The main one is in channelling several skills into writing a series of historical novels about the 'Conquest' era of English history (before the Normans started out on the rest of Britain). The vocabulary and terminology is different, place names sometimes bear no relation to modern-day geography, and the lie of the land was different. Geographical features were described differently - still are, between north and south, east and west - and the land was much more forested. Transport was on a horse or ox, behind a horse or ox - or on water.
People had greatly different names - most no longer used - and those names still in use were spelled differently. Then there's the involvement of outside parties or nationalities involved: Welsh, Irish, Scots, Norse, Dane, Norman, Breton, Frankish, Icelandic... and so on.
In short my research skills needed sharpening before I could start to write.
Whilst I write I need to check my Thesaurus (online and/or paper) for alternative expressions/words. Other sources used are a copy of Domesday and the Chronicles, atlases to show the relationship of locations mentioned in the narrative/dialogue and maps showing the trackways and old Roman roads still in use in the 11th Century.
As an escape from all this i have my steam era railway modelling.with its own vocabulary.
