Cuneiform means wedge-shaped, and the word is used to describe writing that uses wedge-shaped symbols. e.g. Ancient Babylonian inscriptions were in cuneiform. Some alternat…ives to wedge-shaped are cubiform, spherical, spheroid, ellipsoid, rectangular, hexagonal, linear, etc. So what language is the opposite of wedge-shaped? There is no opposite of a wedge, except to say 'non-wedge shaped'! So non-cuneiform is the only possibility, but that doesn't tell use very much! There are many different language styles of writing that are non-cuneiform , e.g. pictographic/graphemic, such as Chinese and Japanese, which use little pictures to represent words or syllables, not alphabetic consonants and vowels; and alphabets that are like a lot of squiggly circles e.g Sinhalese; the Hebrew letter style is sometimes called ketab merubba which means 'square script'; Buginese, which is like a lot of little mountains; and not forgetting Greek, Latin and Arabic writing styles which all differ significantly. So is the 'square style' the opposite of the 'wedge style' or is the 'round style' the opposite of the wedge-style? Is Hebrew the opposite of Babylonian? And what would be the opposite of English? Zulu? .
Having considered different language styles we see that the written symbol form used for any given language does not have an opposite , but that there are many alternative language scripts and symbol styles of language writing. ( Full Answer )
