Editing Celtiberian script (section)

==Typology and variants==
The basic Celtiberian signary contains 26 [[sign (linguistics)|signs]] rather than the 28 signs of the original model; the [[Celtiberians]] omitted one of the two [[rhotic consonant|rhotic]] and one of the three [[Nasal consonant|nasals]] of the [[northeastern Iberian script]]. The remaining 26 signs comprised 5 [[vowel]]s, 15 syllabic signs and 6 consonants (one [[Lateral consonant|lateral]], two [[sibilants]], one rhotic and two nasals). The sign equivalent to Iberian ''s'' is transcribed as ''z'' in Celtiberian, because it is assumed that it sometimes expresses the fricative result of an ancient dental stop (''d''), while the Iberian sign ''ś'' is transcribed as ''s''. As for the use of the nasal signs, there are two variants of the Celtiberian script: In the eastern variant, the excluded nasal sign was the Iberian sign ''ḿ'', while in the western variant, the excluded nasal sign was the Iberian sign ''m''. This is interpreted as evidence of a double origin of the Celtiberian script. Like one variant of the [[northeastern Iberian script]], the western variant of Celtiberian shows evidence{{which|date=March 2014}} of having allowed the [[voice (phonetics)|voiced]] [[Stop consonant|stops]] ''g'' and ''d'' to be differentiated from their respective [[voicelessness|voiceless]] counterparts, ''k'' and ''t'', by adding a stroke to the voiceless signs. This is known as the ‘dual system’ in Paleohispanic scripts, which otherwise do not distinguish between pairs of voiceless and voiced stops (''p:b, t:d'' and ''k:g'').
