As examples of the -sī perfect we may take the preterit of dire ＜ dīcĕre and penre prenre ＜ pr(eh)ĕndĕre:—
(1)
| dīxī | ＞dis, dissí | dīxĭmus ✱dīxĭ́mu’ | ＞dissẹm |
| dīxĭstī | ＞dissíst | dīxĭstis | ＞dissẹtz dissẹs |
| dīxit | ＞dis | dīxĕrunt | ＞dissęron, diron diro |
(2)
| ✱prē(n)sī | ＞pris, prẹs, presí | ✱prē(n)sĭmus ✱prēsĭ́mu’ | ＞presẹm |
| ✱prē(n)sĭstī | ＞presíst | ✱prē(n)sĭstis | ＞presẹtz presẹs |
| ✱prē(n)sit | ＞prẹs | ✱prē(n)sĕrunt | ＞presęron, prẹson, prẹiron |
(3) Escriure ＜ scrībĕre has, beside escris ＜ scrīpsī, a preterit escrius (cf. p. p. escriut escrit escrich), in which the u is probably due to the influence of the infinitive.
(4) For dissí, presí, quesí, respozí, see § [177], (1). For pris prẹs, etc., see § [173], (1).
184. In the -uī perfect the development depends somewhat upon the consonant preceding the u. The treatment of the various cons. + w groups, which was discussed in § [72], may be illustrated by habuit ＞ ac[133], crēvit ✱crēvuit ＞ crẹc[134]; nŏcuit ＞ nǫc[135]; sēdit ✱sĕduit ＞ sęc, pŏtuit ＞ pǫc; valuit ＞ valc[136], tĕnuit ✱tēnuit ＞ tẹnc[137], mĕruit ＞ męrc; sapuit ＞ saup[138]: the noteworthy features are the change of u to -c (through w, gw, g), the absorption of the preceding consonant unless it be a liquid, a nasal, or a p, the preservation of the liquid or nasal, and the metathesis of the p.
Avẹr ＜ habēre, podẹr ＜ ✱pŏtēre pŏsse, volẹr ＜ ✱vŏlēre vĕlle, sabẹr ＜ ✱sapēre sapĕre will serve as examples (for the accentuation of the 3d pers. pl., see § [16], 2):—
