Ludwig's WRAP-UP
The phrase "should have been completed" is a common and grammatically correct way to express that something was expected to be finished by a particular time, but wasn't. As Ludwig AI explains, it conveys regret, expectation, or obligation regarding a past action that wasn't fulfilled. It is suitable for neutral contexts like news articles or professional reports, but clarity is key: always provide context about the expected timeline and reasons for delay. While there are many alternative phrasings, such as "ought to have been finished" or "was supposed to be done", the core meaning remains consistent. Remember to avoid the common error of using "should of" instead of "should have".
