Such suspected allophones/allographs are listed on a common row in the table below. These allographs, called "kar", are diacritical vowel forms and cannot stand on their own. These are not independent letters, but rather allographs. The latter have allographs in English orthography. Prior to that, the former had been merely allographs of the latter. Almost all variants are allographs in most circumstances, such as casual handwriting. Allographs can vary vastly, without affecting the underlying identity of the grapheme.
