Pronunciation: [jˈuːs tuː] (IPA) 
The correct spelling of the phrase "use to" is actually "used to." It is often misspelled as "use to" due to the similarity in pronunciation between the two forms. The correct pronunciation is /juːst tə/ with the stress on the first syllable of "used" and a schwa sound in the second syllable of "to." The expression "used to" is commonly used to refer to something that was done in the past but is no longer done currently.
The phrase "use to" is an idiomatic expression used to describe a past habitual or regular action, behavior, or state that was done repeatedly or customarily in the past but is no longer the case in the present. It is most commonly used in the context of describing past routines, preferences, or familiar experiences.
When used in this manner, "use to" is followed by a base form verb, with the main verb describing the action or behavior that was habitually undertaken. For example, "I used to play the piano every day" indicates that playing the piano was a regular occurrence that no longer happens with the same frequency.
The term "use to" differs from the verb "used to," signifying a state of psychological adaptation or familiarity. It implies a sense of becoming accustomed or acclimated to a particular situation, object, or person. For instance, one might say "I am used to living in a big city" to indicate that they have become comfortable and adjusted to the circumstances of urban living.
In summary, "use to" refers to past habitual actions or behaviors that were done in the past but are not currently practiced. This phrase provides a retrospective insight into the routines, preferences, or familiar experiences of an individual, highlighting that these habits or activities have changed or ceased over time.
The phrase "use to" is considered an informal or colloquial way of expressing the idea that someone was habituated to a certain action or condition in the past. The phrase is derived from the Middle English phrase "used to" or "usid to", which can be traced back to the Old English phrase "gewunod tō". The word "use" in this context refers to the familiar or customary behavior, while "to" emphasizes the habitual nature of the action. Over time, the phrase "used to" contracted to "use to", and it has remained as such in modern English.
