形合与意合是语言结构中的两个重要概念。形合（Hypotaxis）是指句子中的词语或分句之间通过语言形式手段（如关联词）连接起来，表达语法、语义和逻辑关系。意合（Parataxis）则是指句子之间通过隐含的逻辑关系连接，不需要明显的连接词，强调的是句子内容的流畅和简洁。
形合例句
"The idea that the life cut short is unfulfilled is illogical because lives are measured by the impressions they leave on the world and by their intensity and virtue."
"What was the Louvre in Paris like？ It was so interesting that I went several times."
"The cat ate the mouse that ate the malt that lay in the corner of the house."
意合例句
"远看山有色，近听水无声，春去花还在，人来鸟不惊。"
"If winter comes, can spring be far behind？"
"早知今日，何必当初。"
这些例句展示了形合与意合在汉语和英语中的不同表现。汉语注重意合，常常不用或少用连接手段，使句子简洁流畅；而英语注重形合，通过关联词和从句的使用，使句子结构严谨，逻辑清晰。
