Open to objection or criticism; able to be excepted or objected to; questionable or dubious.
From 'exception' + '-able.' Developed in English to describe things that could reasonably be objected to or left out of a category.
This word was much more common in Victorian writing—critics used 'exceptionable' to describe passages or ideas they found fault with, making it essentially a polite way to say 'objectionable.'
