The word 围拢 is formed by combining the character 围, meaning "to surround" or "enclose", with the character 拢, meaning "to gather" or "draw together". Together, they create a compound word where 围 provides the concept of encircling and 拢 adds the action of bringing things inward, resulting in the combined meaning "to gather around" or "to crowd around". This formation directly merges the semantic contributions of each character to convey the idea of people or things closing in from all sides.
