With 本來是用來表達空間上同時存在的「相伴」關係，但也可以延伸做更廣的用法：
A man with long hair → 擁有（長頭髮）
He wrote the letter with caution. → 態度（小心翼翼）
I opened the can with a knife. → 工具（用刀）
後兩句的介系詞片語是用來說明動作的態度及方式，等同於副詞（修飾動詞或形容詞）的功能，也可改用對應的副詞：
He wrote the letter cautiously. = He wrote the letter with caution.
He made the tool manually. = He made the tool with hands.
