The word 备受 is formed by combining the character 备, meaning "fully" or "completely", with 受, meaning "to receive" or "to endure". In this compound, 备 acts as an intensifier modifying 受, resulting in a term that denotes receiving or experiencing something thoroughly or to an extreme extent, such as in 备受煎熬 (enduring intense suffering) or 备受尊敬 (receiving great respect).
