Until I saw your comment I didn't even realize what the sentence was supposed to mean… ._.
"I am hungry" and "I feel hungry" are pretty much synonyms; the first is a bit more emphatic, in the "I want food right now" sense.
There's a similar distinction between "I am full" and "I feel full". The first is polite; the second is calling attention to the idea that you may have already eaten too much.
In Esperanto, "I feel full" would be, Mi sentas min sata.
Nobody would say it. It sounds old-fashioned and pretentious and most people would not think of it.
What is dankon? Noun object verb adverb!!! I couldn't understand it or the other synonyms danko, dankas, danke
"Dankon" is the abbreviation of "Mi donas dankon al vi"
Bonan tagon = Mi deziras al vi bonan tagon.
