Common error
A frequent mistake is writing 'expiration date past' when an action is intended. Use 'passed' as the verb form for the action of time moving by and 'past' as a preposition or adjective to describe a location in time.

Ludwig's WRAP-UP
The phrase "expiration date passed" is a precise and widely recognized way to denote that a product, offer or concept has moved beyond its period of validity. Analysis of Ludwig AI examples shows that while the phrase is grammatically correct as a stand-alone description, it is often part of a larger sentence explaining the disposal of goods or the irrelevance of an idea. It is highly effective in both literal contexts, such as medicine and food safety and metaphorical ones, like describing cultural trends that are no longer in vogue. Writers should be mindful of the 'passed' versus 'past' distinction to maintain professional clarity.
