The word I use is mentoring. I'm not a trainer but I have 40 years experience that I can pass on to my colleagues. Luckily my employer takes command development very seriously and the majority of copilots are keen to improve - they are Captains for the future from day one.
I see this as part of my role and would be sorry to hear of others less inclined to help their fellow pilots.
