danfu, preti, spuda... no solution.
danfu - x1 is the answer/response/solution/[reply] to question/problem x2.
preti - x1 (quoted text) is a question/query about subject x2 by questioner x3 to audience x4.
spuda - x1 answers/replies to/responds to person/object/event/situation/stimulus x2 with response x3.
Robin told me that currently we can say "mi spuda le nu do te preti mi le se du'u preti spuda kei kei dei"which isn't exactly compact.
