Survey means to look at something carefully and completely to understand it better. When you survey a situation, you're taking it all in: examining it from different angles, noticing details, and forming a complete picture. A ship's captain might survey the horizon for other vessels, or a hiker might survey the landscape from a mountaintop to plan the best route down.

The word also means to ask many people the same questions to learn about their opinions or experiences. A school might survey students about what they want for lunch, asking everyone to answer the same questions so they can see patterns in the responses. Politicians survey voters to understand what issues matter most. Scientists survey people to gather information for research. When used this way, survey can also be a noun: you might fill out a survey about your favorite books or TV shows.

In another sense, surveying means measuring land precisely to create maps or determine property boundaries. A surveyor uses special instruments to measure distances and angles, marking exactly where one person's land ends and another's begins. This kind of surveying has been crucial throughout history for building roads, planning cities, and settling disputes about who owns what land.

The common thread in all these meanings is careful, systematic observation: looking at something thoroughly to gather accurate information.
