Context: <response>: ```While Old Czech get basic alphabet wey dem use draw general set of orthographical correspondences, e no get standard orthography. E still get some sound clusters wey no dey exist again; like allowing ě (/jɛ/) after soft consonants, wey don shift to e (/ɛ/), and allowing complex consonant clusters make dem pronounce am all at once instead of syllabically. One phonological phenomenon, Havlik's law (wey start for Proto-Slavic and get different forms for other Slavic languages), show for Old Czech; as dem dey count backwards from the end of a clause, every odd-numbered yer dey vocalized as a vowel, while the other yers disappear.```
