Stylistics of composite sentences

Between the parts of a composite sentence there are relations such as cause-effect, purpose, condition, concession and time. These relations can be expressed with linking means or without them; accordingly synonymous constructions arise: «Kech qoldim, chunki avtobus kechikdi» (“I was late because the bus was delayed”) – «Avtobus kechikdi, shuning uchun kech qoldim» (“The bus was delayed, so I was late”) – «Kech qoldim: avtobus kechikdi» (“I was late: the bus was delayed”). In a sentence with a conjunction the relation is shown openly, in one without it the relation is understood through intonation and meaning. In the scientific and official styles sentences with conjunctions are preferred to give the content fully and exactly; in conversation long, complex sentences are rarely built and conjunctionless or simple sentences are used more. In the artistic and publicistic styles all kinds are used depending on the description and tone. In a conjunctionless sentence a colon (:) is usually put when the next part explains the previous one or gives the cause, while a dash (–) is used for contrast, time, result or condition-consequence.
