The Japanese verb 'よこす (yokosu)' primarily means 'to send' something to someone, often implying the movement of an object or message from one place to another. It can also mean 'to cause' something, typically something negative or troublesome. For example: I will send you the documents「書類をよこします」(しょるいをよこします). His behavior caused a lot of trouble「彼の行動は多くの問題をよこした」(かれのこうどうはおおくのもんだいをよこした). The verb is commonly used in both formal and informal contexts, and its meaning can slightly shift depending on the situation.
