When it comes to describing a task or work that is not completed as it should be, there are many synonyms that can be used for 'job half-done'. Some of the common terms we often use include incomplete, unfinished, unaccomplished, undone, half-finished, not completed, unfulfilled, half-baked, and partial. These terms imply that the task at hand may have been started but not given the necessary attention to complete it successfully. Such terminologies are often used in our daily conversation to express disappointment or to indicate that more work needs to be done. Whatever the context, using the right synonym can help in conveying the right message.
