The difference may be partially one of dialect. There are a few such words that are disyllabic, like cursor, curtain, and turtle: , and (or , , and ), and even a few that are trisyllabic, at least in some accents, such as purpler , hurdler , gurgler , and certainer . The word and frequently contracts to a simple nasal ’n, as in lock 'n key . Words such as will, have, and is regularly contract to ’ll , ’ve , and 's . However, none of them are pronounced alone without vowels, so they are not phonological words. Onomatopoeic words that can be pronounced alone, and that have no vowels or ars, include hmm, pst!, shh!, tsk!, and zzz. As in other languages, onomatopoeiae stand outside the normal phonotactics of English. There are other languages that form lexical words without vowel sounds. In Serbo-Croatian, for example, the consonants and (the difference is not written) can act as a syllable nucleus and carry rising or falling tone; examples include the tongue-twister and geographic names such as . In Czech and Slovak, either or can stand in for vowels: "wolf", "neck". A particularly long word without vowels is , meaning "quarter-handful", with two syllables (one for each R), or , a verb form meaning "you flipped (sth) down" (eg a marble). Whole sentences (usually tongue-twisters) can be made from such words, such as , meaning "stick a finger through your neck" (), and . (Here has two syllables based on L; and note that the preposition consists of a single consonant. Only prepositions do this in Czech, and they normally link phonetically to the following word, so not really behave as vowelless words.) In Russian, there are also prepositions that consist of a single consonant letter, like , , and . However, these forms are actually contractions of , , and respectively, and these forms are still used in modern Russian before words with certain consonant clusters for ease of pronunciation. In Kazakh and certain other Turkic languages, words without vowel sounds may occur due to reduction of weak vowels. A common example is the Kazakh word for one: , pronounced . Among careful speakers, however, the original vowel may be preserved, and the vowels are always preserved in the orthography. In Southern varieties of Chinese, such as Cantonese and Minnan, some monosyllabic words are made of exclusively nasals, such
