Definition of look through

The origin of the phrase "look through" can be traced back to the late 14th century when the expression "looken acres" was used in Old English to mean "to see through" or "to peer into". In Middle English, the phrase evolved into "loke mare", which meant "to look far". During the 16th century, the phrase "look throughout" appeared in the English language, which was a combination of the words "look" and "throughout". This phrase eventually became "look through", which refers to the action of looking at something while peering through an object or a substance, such as a window, a book, or a material. Another possible origin of the word "look through" comes from the Middle English verb "thynken", meaning "to thin" or "to make thin". The word became "thynke" in the Early Modern English language, and this root word is evident in the phrase "thin book", which means a book with few pages or content. In this sense, the expression "look through" could also refer to the act of examining or reading something quickly and easily, as if it were thin or transparent. Overall, the phrase "look through" has evolved over time and has been shaped by the evolution of the English language, with its roots in Old and Middle English words that describe the actions of seeing, peering, and examining objects or materials.
