I think the problem you and I are having is the meaning of the word "specific". We are not talking here of "steci", but more like the following definitions of specific from
m-w.com:
1a : constituting or falling into a specifiable category
b : sharing or being those properties of something that allow it to be referred to a particular category
4 of, relating to, or constituting a species and especially a biological species
i.e. klesi or jutsi
When I say "mi me la'oi turniansky" It means "I am of the category/species Turniansky" If I say "mi me lao'i Turniansky lo ka jbena" it means "I am Turnainsky by birth"
