In a way that relates to a hobby or interest rather than a profession.
She pursued her painting avocationally, enjoying it as a relaxing pastime.
Avocationally → It is formed from "avocation" (from Latin "avocatio", meaning a calling away) and the adverbial suffix "-ally" (meaning in a manner relating to). The word "avocationally" refers to doing something in a manner that is related to an activity pursued outside of one's main profession or vocation.
Think of 'avocation' as a calling away from your main job, and the '-ally' means in that manner. So, avocationally means doing something related to that calling away.
