Gamblesome

"That's very gamblesome." / (!) / I'm speechless. (But, fortunately, not wordless.) / If you're not nonplused by "gamblesome," or at least vastly taken aback, there's probably no hope for the language.

In an article in English on “The Adventurers” in the play, we learn that “nearly every character turns out to be an adventurer, with a particular gamblesome [sic] tendency of his own” (30).
