'Anjou-associated' is a compound formed from French 'Anjou' (the name of the historical province/territorial family) and English 'associated' (from Latin 'associare'), where 'Anjou' denotes the place or dynasty and 'associated' means 'joined or connected'.

'Anjou' derives from Gallo-Roman/Latin 'Andegavia' (attested as 'Andegavum'), which passed through Old French (e.g. 'Anju') to modern French 'Anjou'; 'associate' comes from Latin 'associare'/'associatus' ('ad-' + 'socius' meaning 'companion, ally') via Old French/Medieval Latin into Middle English, producing the modern English 'associated'.

Originally the place-name 'Anjou' identified a specific region and ruling house; combined with the English adjective 'associated', the compound came to mean 'connected with Anjou' in the modern descriptive sense.
