Nowadays the Lithuanian alphabet is shaped on the basis of the Latin alphabet and consists of 32 letters. It uses such diacritics as:

(“ˇ”) above č, š, ž,
(“˛”) - ą, ę, į, ų ,
a horizontal line above ū meaning longitude
and a point above ė  indicating a long, narrow and tense vowel.

Writing is phonetic, with elements of historical writing – e.g. ą, ę, į, ų used to mean that the vowels in question were to be nasalized – today, however, their pronunciation does not differ from the pronuciation of long vowels [a:], [æ:], [i:], [u:], that is why their spelling has purely historical meaning (Vaičiulytė-Romančuk 2006: 11Vaičiulytė-Romančuk 2006 / komentarz/comment/r /
