What does surveyor mean?
A surveyor is a professional who measures, examines, and records information about land, property, buildings, or other subjects. Surveyors establish boundaries, calculate areas and dimensions, assess site conditions, and prepare the measurements that support maps, property transactions, construction projects, and legal documentation. The word can also describe someone who gathers information through a questionnaire or systematic inquiry, although its strongest everyday association is with land and property measurement. A quantity surveyor is a related professional role concerned particularly with the quantities, costs, and specifications of construction work. In legal and property contexts, the work of a surveyor can determine ownership boundaries and affect the value or practical use of land. The word is useful because it identifies the person responsible for turning direct observation and measurement into reliable technical information.
A person whose occupation is to measure and examine land, buildings, or other property in order to establish boundaries, dimensions, condition, or value.
"A licensed surveyor prepared the report identifying the exact property boundary."
The compound quantity surveyor is especially associated with construction cost and quantity assessment.
A person who conducts a systematic survey or inquiry, especially by collecting information from respondents.
"The surveyors explained the purpose of the study and invited residents to complete the questionnaire."
The regular plural is used for both land and property professionals and people conducting questionnaires or other systematic inquiries.
"Several surveyors visited households to conduct the study."
Without surveyors, maps, property boundaries, and the careful measurements behind modern construction would be far less trustworthy.

Where does surveyor come from?
The word entered Middle English from the Anglo-French and Old French forms, ultimately relating to Latin roots meaning “to look over” or “to examine.” The modern form developed alongside the older English noun survey and the verb survey. Its underlying connection is with looking carefully over an area, which explains both the original meaning and the later professional sense involving measurement and inspection.
How surveyor is actually used
The term is most common in professional and legal contexts, especially in relation to land, property, construction, and engineering. In British English, a quantity surveyor assesses construction costs and quantities, while in American English the term may sometimes be used for a person who performs general land or property surveys.
