léi 现代普通话 Modern MandarinAI 合成语音 AI-generated voice
与「雷」有关的早期字形包含闪电形的线条和圆形。字库把圆形解释为车轮，以车轮声比拟雷声；后来又加上表示雨的「雨」。 Early forms associated with 雷 combine a lightning-like line and round shapes. CUHK interprets the rounds as wheels suggesting a rumbling sound. Later forms added 雨, the rain element.
分类依据 Why these classifications?
传统六书分类可以交叉。前四类描述构形，假借与转注涉及用字或字词关系。标签可能对应不同历史或现代字形。问号表示暂定或传统解释；打开汉字可查看依据。 The six traditional classifications (六书) overlap. The first four describe construction; loangraphs and derivative cognates concern use or relationships. Tags may refer to different historical or modern forms. A question mark flags a provisional or traditional interpretation; open a character for its evidence.
会意 Compound ideographs 雷
暂定分析 Provisional analysis中大字库把早期字形解释为闪电与表示隆隆声的车轮形相组合，后来加雨。这是一种构形解释，并非说现代的田形表示农田。
CUHK interprets the early graph as lightning plus circular wheel forms suggesting rumbling sound; 雨 was added later. This compound account is an interpretation, not a claim that the modern 田 means a field.

以车轮声比拟雷声是一种解释；按此说，今字下部虽像「田」，却不表示农田。 The wheel-and-rumble account is an interpretation. The modern 田-shaped lower part does not mean a field in this account.
