I think I saw this in another post, but I can't find it now...
Can you use adjectives to denote possession? I was reading this cute Christmas story and saw this usage:
En la patrina koro
and this:
en la patraj okuloj
The only way I can understand this is as "in the mother's heart..." and "in the father's eyes". Is this correct? Is this common, or just a very poetic turn of phrase?
