About the particle; pure and functional; interrogative particles

Particles are auxiliary means that give an additional shade of meaning to a word or a whole sentence. With them, meanings of question, intensifying, singling out, doubt, likeness or negation are expressed. By form, particles fall into two groups. Those written as separate words are word-particles: faqat, hatto, axir, ham, xuddi, go‘yo, nahotki, sira and others. Those attached to a word like a suffix are suffix-particles: -mi, -chi, -gina, -dir, -u (-yu), -da, -a (-ya) and the like. A particle is not a sentence member and answers no question: in “Hatto bobom ham raqsga tushdi” (Even my grandfather danced too) “hatto” and “ham” only add emphasis.
