[202]. Formative suffixes are often preceded by a vowel, which in many instances is a stem vowel, real or presumed; in others, the vowel has come to be regarded as a part of the suffix itself.
Thus, -lo-: fīlio-lo-, N. fīlio-lu-s, little son (fīlio-); hortu-lu-s, little garden (horto-, [105, h]); but -ulo-: rēg-ulu-s, petty king (rēg-); ger-ulu-s, porter (√ges-, bear), -ci-: pugnā-ci-, N. pugnā-x, full of fight (pugnā-re); but -āci-: fer-āx, productive (√fer-, bear), -to-: laudā-to-, N. laudā-tu-s, praised (laudā-re); but -āto-: dent-ātus, toothed (denti-). -tu-: equitā-tu-, N. equitā-tu-s, cavalry (equitā-re); but -ātu-: sen-ātu-s, senate (sen-). -lā-: suādē-lā-, N. suādē-la, persuasion (suādē-re, [192]); but -ēlā-: loqu-ēla, talk (√loqu-, speak). -tāt-: cīvi-tāt-, N. cīvi-tā-s, citizenship (cīvi-); but -itāt-: auctōr-itā-s, authority (auctōr-). -cio-: aedīli-cio-, N. aedīli-ciu-s, of an aedile (aedīli-); but -icio-: patr-iciu-s, patrician (patr-). -timo-: fīni-timo-, N. fīni-timu-s, bordering (fīni-); but -itimo-: lēg-itimu-s, of the law (lēg-).
[203]. There are many formative suffixes of nouns. The commonest only can be named, and these may be conveniently grouped as below, by their meanings. Compound suffixes are arranged with reference to the last element of the suffix: thus, under the adjective suffix -io- ([304]) will be found -c-io-, -īc-io-, -tōr-io-, and -ār-io-. In many instances it is difficult to distinguish between simple and compound suffixes.

[204]. The suffixes -tōr-, -o-, -ā-, -lo-, and -ōn-, are used to denote the Agent: as,

| scrīb-ā- | scrība, writer | √scrīb-, write |
