<sod>In the earliest [[Latin]] inscriptions, the letters C, K and Q were all used to represent the two sounds {{IPA|/k/}} and {{IPA|/ɡ/}}, which were not differentiated in writing.  Of these, Q was used before a rounded vowel (e.g. {{angbr|EQO}} 'ego'), K before /a/, and C elsewhere.  Later, the use of C (and its variant G) replaced most usages of K and Q:  Q survived only to represent /k/ when immediately followed by a /w/ sound.<ref>{{citation <eod>
