Synonymy of subordinate composite sentences with simple sentences

A subordinate composite sentence whose main clause has a demonstrative pronoun (u, shu, o‘sha, shunga) can often be replaced by a simple sentence with the same meaning. We put the content of the subordinate clause where the pronoun stands: the predicate of the clause becomes a participle (-gan) or a verbal noun (-ish), and the whole clause turns into one sentence part. For example: “Kim tinmay mashq qilsa, u g‘olib bo‘ladi” – “Tinmay mashq qilgan g‘olib bo‘ladi”. “Shuni bilamanki, u halol” – “Men uning halolligini bilaman”. The meaning of both is the same but the style differs: the composite sentence is freer and more expressive, the simple one more compact. When changing, the endings must agree and the meaning must not be broken.
