Q is only used rarely (Sequanni, Equos) and may represent an archaism (a retained *kw) or, as in Latin, an alternate spelling of -cu- (for original /kuu/, /kou/, or /kom-u/).[57] Ð and ð are used to represent the letter Ð (tau gallicum, the Gaulish dental affricate).

 * long: ā, ē, ī, (ō), ū
 * diphthongs: ai, ei, oi, au, eu, ou

Sound laws

 * Gaulish changed the PIE voiceless labiovelar kʷ to p, a development also observed in the Brittonic languages (as well as Greek and some Italic languages like the Osco-Umbrian languages), while other Celtic languages retained the labiovelar. Thus, the Gaulish word for "son" was mapos,[58] contrasting with Primitive Irish *maq(q)os (attested genitive case maq(q)i), which became mac (gen. mic) in modern Irish. In modern Welsh the word map, mab (or its contracted form ap, ab) is found in surnames. Similarly one Gaulish word for "horse" was epos (in Old Breton eb and modern Breton keneb "pregnant mare") while Old Irish has ech, the modern Irish language and Scottish Gaelic each, and Manx egh, all derived from proto-Indo-European *h₁eḱwos.[59] The retention or innovation of this sound does not necessarily signify a close genetic relationship between the languages; Goidelic and Brittonic are, for example, both Insular Celtic languages and quite closely related.
 * The Proto-Celtic voiced labiovelar *gʷ (From PIE *gʷʰ) became w: *gʷediūmi → uediiumi "I pray" (but Old Irish guidim, Welsh gweddi "to pray").
 * PIE ds, dz became /tˢ/, spelled ð: *neds-samo → neððamon (cf. Irish nesamh "nearest", Welsh nesaf "next"). Modern Breton nes and nesañ "next".
 * PIE eu became ou, and later ō: *teutā → touta → tōta "tribe" (cf. Irish tuath, Welsh tud "people").
 * Additionally, intervocalic /st/ became the affricate [tˢ] (alveolar stop + voiceless alveolar stop) and intervocalic /sr/ became [ðr] and /str/ became [θr]. Finally, when a labial or velar stop came before /t/ or /s/, the two sounds merged into the fricative [χ].

Word order
Most Gaulish sentences seem to consist of a subject–verb–object word order:
