Capable of being bemoaned; worthy of lamentation or regret.
From 'bemoan' + the suffix '-able' (from Latin '-abilis', meaning capable of). This suffix allows any verb to become an adjective meaning 'able to be' or 'worthy of being'.
The '-able' suffix is one of English's most productive tools for wordbuilding—you can attach it to almost any verb and native speakers will understand the new word immediately, even if they've never heard it before.
