The quality or state of being somewhat blunt; a moderate degree of dullness or directness.
From 'bluntish' plus the abstract noun suffix '-ness,' which creates nouns from adjectives. This double suffix pattern (-ish + -ness) shows English's flexibility in building new words.
Words with '-ness' endings let us talk about invisible things—'bluntishness' exists only in conversation and thought, not in the physical world, which is what abstractions do.
