Speech styles and stylistic colouring

Many words are adapted to a certain style and become a mark of it. A word’s belonging to a certain style is called functional colouring: for example the phrase «ravona bo‘lmoq» (“to set off”), unlike neutral «ketmoq» (“to go”), is bookish and typical of elevated written style. Some words also express the speaker’s positive or negative attitude to the thing; this is called emotional-expressive colouring. For example «jilmaymoq» (to smile) is neutral or warm, while «irjaymoq» (to grin unpleasantly) expresses a negative evaluation. Functional and emotional-expressive colouring together are called stylistic colouring. One word can have both kinds, so before choosing a word one must know its colouring as well as its meaning.
