The phrase "turned in to" can be confusing for non-native speakers because it sounds the same as "turned into" when pronounced. However, "turned in to" is two separate words, "turned" (tɜːnd) and "in" (ɪn), followed by the preposition "to" (tuː). Meanwhile, "turned into" is a phrasal verb that means to transform or change, and is pronounced as a single entity (tɜːndɪntuː). It's essential to pay attention to spelling and pronunciation to ensure proper communication in English.
"Turned in to" is a phrasal verb that typically denotes the action of surrendering or delivering someone or something to a particular authority or destination. It implies a change in the nature or status of the subject, usually involving a process of transformation, submission, or conversion.
In the context of personal belongings or lost items, "turned in to" refers to the act of delivering or submitting something to a person or establishment responsible for its safekeeping or appropriate handling. For instance, if someone finds a lost wallet on the street and takes it to the local police station, they have "turned it in to" the authorities. Similarly, if a student completes an assignment and hands it over to the teacher, they have "turned it in to" signify their submission.
This phrase can also describe a more metaphorical or abstract transformation. For example, an individual with criminal behavior can "turn themselves in to" the police, meaning they voluntarily surrender and acknowledge their wrongdoing. Additionally, it can be used to indicate a conversion or change of state, such as a substance being "turned in to" gas when exposed to heat or a caterpillar being "turned in to" a butterfly through the process of metamorphosis.
In summary, "turned in to" refers to the act of delivering, surrendering, or converting someone or something to a specific authority or destination, either literally or metaphorically.
