No, its not possible. The problem is financial is an adjective. Financials
is not proper English, however it has come into our language as a noun, for
example Oracle Financials.

So strictly speaking these words are not related, searching on financial
should not return hits to financials, similarly searching on train (in the
context of steam training) should not match with training (i.e. I am
training for a marathon).

What language are you searching in?

You could use the thesaurus option in a Freetext search for this
functionality or write your own word breaker.

I use the FORMSOF(INFLECTIONAL, ...) when I create my searches from a user's
entry.  A coworker has just pointed out that when she searches for
"financial", the search does not return matches with the word "financials"
it it.

Is it possible to add this word pair to Full-Text search, or update the
dictionary FTS uses?

I'm using SQL Server 2k
