The possessive particle 的

Structure Possessor + 的 + thing

的 (de) links a modifier to the noun it describes; the most typical case is possession: 我的书 ("my book"), 老师的车 ("the teacher’s car"). It always goes BETWEEN the owner and the thing. With very close relations (family, "my" group) it is usually dropped: 我妈妈, 我们老师.
