The coherence beetween the modelling principles we adopt and common
language definitions is a strong argument to me. This means we're not that
wrong, and that any person can understand. It's just essential that the two
are consistent, as we're trying in WIkidata to define topics the best we
can, just as Wikipedia articles does. This implies that we also will get
some kind of international language with statements that reflects the
subtelety of the definitions of the different languages.

I also strongly values the "1 item = 1 definition" principle, even at the
cost of item disconnections if definitions of some close notions in
different language.
