of ruka is ruke. The Ukrainian language, in common with Serbo-Croatian and Slovene, has developed the ending -mo for first-person plurals in verbs (khodymo for "we walk"). In all cases, it resulted from lengthening of the Common Slavic -mŭ. The Ukrainian language, along with Russian and Belarusian, has changed the Common Slavic word-initial ye- into o, such as in the words ozero (lake) and odyn (one). The Ukrainian language, in common with Czech, Slovak, Upper Sorbian, Belarusian and southern Russian dialects, has changed the Common Slavic "g" into an "h" sound (for example, noha – leg). The Ukrainian language, in common with some northern Russian and Croatian dialects, has transformed the Common Slavic yě into i (for example, lis – forest). The Ukrainian language, in common with Russian, Belarusian, Bulgarian, Serbo-Croatian, Macedonian, and Slovene, has simplified the Common Slavic tl and dl into l (for example, mela – she swept"). The Ukrainian language, in common with the most of Slavic ones, is a stress-timed language, in which syllables may last different amounts of time, but there is perceived to be a fairly constant amount of time (on average) between consecutive stressed syllables. The Ukrainian language, in common with all modern Slavic languages other than Bulgarian and Macedonian, does not use articles. Other Slavic o in closed syllables, i.e., syllables ending in a consonant, in many cases corresponds to a Ukrainian i, as in pod → pid (під, 'under'). This also includes place names such as Lviv (Львів in Ukrainian), Lwów in Polish, and Львов (Lvov) in Russian. Unlike all other Slavic languages, Ukrainian has a synthetic future (also termed inflectional future) tense which developed through the erosion and cliticization of the verb "to have" (or possibly "to take"): pysat-ymu (infinitive-future-1st sg.) I will write. Although the inflectional future (based on the verb 'to have') is characteristic of Romance languages, Ukrainian linguist A. Danylenko argues that Ukrainian differs from Romance in the choice of auxiliary, which should be interpreted as 'to take' and not 'to have.' He states that Late Common Slavic (LCS) had three verbs with the same Proto-Indo-European root : a determined imperfective LCS *jęti: *jĭmǫ 'to take' (later superseded by numerous prefixed perfectives) an indetermined imperfective LCS *jĭmati: jemljǫ 'to take' (which would not take any prefixes) an imperfective LCS *jĭměti: *jĭmamĭ 'to hold, own, have' The three verbs became conflated in East Slavic due to morphological overlap,
