属格（genitive case），亦称所有格、领格，是指名词的语法上的格。属格表示一个名词的所属。
关系代词用来引导定语从句，它代表先行词，同时在从句中作一定的句子成分。关系代词有主格，宾格和属格之分
主格: who, that, which。如The woman who is standing there is our Chinese teacher. 句中关系代词who是主格，是从句is standing there的主语。
宾 格: whom, that, which。如 I can't remember the man whom I gave the key to. 句中关系代词whom是宾格，做介词to的宾语。
属 格: whose, of which/whose。如She is looking after the little child whose parents are abroad。句中关系代词whose是属格，修饰限定从句中主语parents, 做其定语，相当于his。
