Expert writing Tips
Best practice
This phrase is particularly effective in legal or investigative writing to describe a person's inability to provide a statement based on memory.
Common error
Do not add redundant words like "completely" or "entirely" if the context already implies a total failure. While "completely unable" is grammatically correct, "be unable to remember" already conveys a binary state of incapacity in most professional contexts.

Ludwig's WRAP-UP
The phrase "be unable to remember" is a highly reliable and grammatically standard construction used to denote a specific cognitive or situational inability to access stored information. According to Ludwig AI, it is most prevalent in high-authority sources like The New York Times and scientific journals, where precision regarding memory failure is required. While it shares semantic space with simpler verbs like "forget", it carries a more clinical and objective tone, making it ideal for reporting on trauma, legal testimony or neurological studies. Writers should prioritize this phrase when they wish to emphasize the incapacity rather than just the act of forgetting. Alternatives such as "cannot recall" offer similar formality, while "draw a blank" is better suited for casual contexts.
