Welcome to your grammar training system! When discussing childhood habits or historic lifestyles, using the correct structure signals high linguistic capability. Today, we target the expression used to, which allows us to bridge past activities directly with changes in our current environment.

Structural Formulations
We use the indicator used to explicitly for repetitive past actions or obsolete realities that are no longer true today. It is always followed directly by the base, uninflected form of your action verb.
Example 1: I used to draw sketches on raw paper, but now I design on an interactive digital tablet.
Example 2: I used to live in Phnom Penh before relocating to a quiet studio in Kampot.
Example 1: I didn't use to like coffee, but now I rely on it every single morning.
Example 2: We didn't use to have high-speed fiber internet in the local district villages.
Example 1: Did you use to watch traditional animation broadcasts when you were young?
Example 2: What did you use to do for fun before smart technology infrastructure arrived?
A frequent constraint is keeping the letter d on the word "use" inside negative phrases or questions. Because the helper token Did or Didn't already indicates the past era, you must reset the word to its base spell form.
Never apply this structure for an action that occurred exactly one single time in history. For isolated instances, use the standard Past Simple tense instead.
