I think that this is just a coincidence, because it's very unlikely that these words are related, but the coincidence is remarkable so I wanted to ask it anyway. Lithuanian is Indo-European and belongs to the Baltic languages and Arabic is Afro-Semitic and is not related to Indo-European languages, although this is true you have the words 'Galbut' in Lithuanian and 'Galiba' in Arabic. Galbut means: 'he can', if I am right (correct me if I am wrong because I am not completely sure) and Galiba means 'maybe'. The word 'maybe' also means 'can be' sometimes, in French for instance, maybe means 'peut-être' (literally: can be). I thought that it's remarkable how the first 4 letters are very similar: galb.. and I wondered if they are in some way related, if this is maybe a borrowing from one to the other or is this just a remarkable coincidence between these languages?
