Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the

Of these, '' was used to represent or before a rounded vowel, '' before '', and '' elsewhere. During the 3rd century BC, a modified character was introduced for , and '' itself was retained for . The use of '' (and its variant '') replaced most usages of '' and ''. Hence, in the classical period and after, '' was treated as the equivalent of Greek gamma, and '' as the equivalent of kappa; this shows in the romanization of Greek words, as in 'ΚΑΔΜΟΣ', 'ΚΥΡΟΣ', and 'ΦΩΚΙΣ' came into Latin as '', '' and '', respectively. Other alphabets have letters homoglyphic to 'c' but not analogous in use and derivation, like the Cyrillic letter Es (С, с) which derives from the lunate sigma, named due to its resemblance to the crescent moon.
