The Origin of Use To or Used To
The phrase “used to” comes from Old English and means something that was normal in the past. Over time, pronunciation changed. When people spoke fast, “used to” sounded like “use to.”
This spoken sound caused writing confusion. Grammatically, “did” already shows the past tense. So the verb goes back to its base form “use.” That is why “use to” appears in questions and negatives.
The spelling difference is not about style. It is about grammar structure.
