Orberg, LLPSI, ch xxxiv, §229 wrote:"Syllaba brevis est quae in vocalem brevem (a,e,i,o,u) desinit; quae desinit in vocalem longam (ā, ē, ī, ō, ū) aut in diphthongum (ae, oe, au, ei, ui) aut in consonantem (b, c, d, f, g, l, m, n, p, r, s, t, x) syllaba longa est."
Hîc q littera in consonantum tabulâ non includitur quod nulla syllaba in q litteram latinè desinere potest. Manet autem consonans haec littera. Meliùs, ut opinor, scripsisset "ut" ante hanc consonantum tabulam vel nullum ante, ne eam inclusisset inter parentheses (seu uncas).Here he doesn't include q in the list of consonants because a syllable can't end in q in Latin. It remains a consonant, however. Better, I think, if he had put nothing or "as" before the list, rather than put it in brackets.
I'm writing in Latin hoping for correction, and not because I'm confident in how I express myself. Latinè scribo ut ab omnibus corrigar, non quod confidenter me exprimam.
