Not heavy and easy to carry or wear.
用法模式：
a lightweight [object]
常见错误：
Learners sometimes use only "light" instead of "lightweight" before nouns (e.g., *"a light jacket" vs. "a lightweight jacket"). Both are possible, but "lightweight" more strongly emphasizes that the thing is made to be easy to carry or wear.
近义词
light (Very common general word; can describe weight, color, or intensity, while "lightweight" only describes weight.)

not serious or important; shallow
Not very serious, deep, or important; simple and easy to think about.
用法模式：
a lightweight [thing/idea]

近义词
shallow (Often describes people or ideas that are not deep; can sound more negative and judgmental than "lightweight".)
反义词
serious (Emphasizes that something deals with important or difficult ideas or problems.)
