What Does "used to" Mean?
- What it expresses: The expression "used to" primarily functions in two ways. As a semi-modal verb, it expresses time and frequency, specifically referring to habits or states that existed in the past but no longer occur. As an adjective phrase (be used to), it expresses a state of familiarity or accustomization.
- What part of the sentence it typically modifies: It modifies the verb (in the case of past habits) or describes the subject (in the case of familiarity).
- Register: Neutral. It is appropriate for both informal conversation and formal writing, though "would" is sometimes preferred in formal narratives for repeated past actions.
How to Use It
- Typical sentence positions: It usually occupies the mid-position, appearing directly before the main verb (e.g., "I used to smoke"). In the "familiarity" sense, it follows a form of the verb "to be."
- What it modifies and how it changes the meaning: It shifts the timeframe of a sentence to a finished past. Saying "I live here" is a present fact; "I used to live here" implies you no longer do.
- Grammatical flexibility: It can be used with negation ("didn't use to") and in questions ("Did you use to?"), though the spelling often drops the 'd' in these cases. It cannot easily be fronted to the beginning of a clause.
- What sounds unnatural or incorrect: Using "used to" for a single event in the past (e.g., "I used to go to the store once last Tuesday") is incorrect; it must refer to a repeated action or a state.

Common Mistakes
- Wrong Form in Negatives: Writing "didn't used to" with a 'd' is technically incorrect in most formal grammar guides, as the auxiliary "did" already carries the past tense; "didn't use to" is preferred.
- Confusion with "would": Using "would" for past states (e.g., "I would be a child") is incorrect; "used to" must be used for states, while "would" is only for actions.
- The Most Common Error: Learners often confuse the past habit used to with the stative adjective be used to, leading to errors like "I am used to wake up early" instead of "I used to wake up early" or "I am used to waking up early."

FAQs
Where in a sentence should used to appear?
The expression used to typically occupies the mid-position of a sentence. When describing a past habit, it is placed directly before the base form of the verb. In the context of familiarity, it follows the verb to be.
What is the difference between used to and would?
While both describe past actions, used to can describe both past states and repeated actions. In contrast, would is strictly reserved for repeated actions and cannot be used for past conditions like "being tall" or "living in London."
How do I avoid confusing past habits with familiarity?
To describe a past habit, use used to followed by a verb. To describe being accustomed to something, use a form of be used to followed by a noun or a gerund. Remember that "I am used to waking up" refers to a current comfort level, while "I used to wake up" refers to a finished habit.
