PERIPHRASTIC CONJUGATION.

115. There are two Periphrastic Conjugations, - the Active and the Passive. The Active is formed by combining the Future Active Participle with the auxiliary sum, the Passive by combining the Gerundive with the same auxiliary.

Active Periphrastic Conjugation.

INDICATIVE MOOD.
Pres. amātūrus (-a, -um) sum, I am about to love.
Inf. amātūrus eram, I was about to love.
Fut. amātūrus erō, I shall be about to love.
Perf. amātūrus fuī, I have been (was) about to love.
Plup. amātūrus fueram, I had been about to love.
Fut. P. amātūrus fuerō, I shall have been about to love.

SUBJUNCTIVE.
Pres. amātūrus sim, may I be about to love.
Imp. amātūrus essem, I should be about to love.
Perf. amātūrus fuerim, I may have been about to love.
Plup. amātūrus fuissem, I should have been about to love.

INFINITIVE.
Pres. amātūrus esse, to be about to love.
Perf. amātūrus fuisse, to have been about to love.

Passive Periphrastic Conjugation.

INDICATIVE.
Pres. amandus (-a, -um) sum, I am to be loved, must be loved.
Imp. amandus eram, I was to be loved.
Fut. amandus erō, I shall deserve to be loved.
Perf. amandus fuī, I was to be loved.
Plup. amandus fueram, I had deserved to be loved.
Fut. P. amandus fuerō, I shall have deserved to be loved.

SUBJUNCTIVE.

Imp. amandus essem, I should deserve to be loved.
Perf. amandus fuerim, I may have deserved to be loved.
Plup. amendus fuissem, I should have deserved to be loved.

INFINITIVE.
Pres. amandus esse, to deserve to be loved.
Perf. amantus fuisse, to have deserved to be loved.


PECULIARITIES OF CONJUGATION.

116. 1. Perfects in -āvī, -ēvī, and -īvī, with the forms derived from them, often drop the ve or vi before endings beginning with r or s. So also nōvī (from nōscō) and the compounds of mōvī (from moveō). Thus: -

amāvistī amāstī dēlēvistī dēlēstī
amāvisse amāsse dēlēvisse dēlēsse
amāvērunt amārunt dēlēvērunt dēlērunt
amāverim amārim dēlēverim dēlērim
amāveram amāram dēlēveram dēlēram
amāverō amārō dēlēverō dēlērō
nōvistī nōstī nōverim nōrim
nōvisse nōsse nōveram nōram
audīvistī audīstī audīvisse audīsse

2. In the Gerund and Gerundive of the Third and Fourth Conjugations, the endings -undus, -undī, often occur instead of -endus and -endī, as faciundus, faciundī.

3. Dīcō, dūcō, faciō, form the Imperatives, dīc, dūc, fac. But compounds of faciō form the Imperative in -fice, as cōnfice. Compounds of dīcō, dūcō, accent the ultima; as, ēdū´c, ēdī´c.

4. Archaic and Poetic forms: -

a. The ending -ier in the Present Infinitive Passive; as, amārier, monērier, dīcier, for amārī, monērī, dīcī.

b. The ending -ībam for -iēbam in Imperfects of the Fourth Conjugation, and -ībō for -iam in Futures; as, scībam, scībō, for sciēbam, sciam.

c. Instead of the fuller forms, in such words as dīxistī, scrīpsistis, surrēxisse, we sometimes find dīxtī, scrīpstis, surrēxe, etc.

d. The endings -im, -īs, etc. (for -am, -ās, etc.) occur in a few Subjunctive forms; as, edim (eat), duint, perduint.

5. In the Future Active and Perfect Passive Infinitive, the auxiliary esse is often omitted; as, āctūrum for ācturum esse; ējectus for ējectus esse.



FORMATION OF THE VERB STEMS.

Formation of the Present Stem.

117. Many verbs employ the simple Verb Stem for the Present Stem;[39] as, dīcere, amāre, monēre, audīre. Others modify the Verb Stem to form the Present, as follows: -

1. By appending the vowels, ā, ē, ī; as, -

Present Stem Verb Stem
juvāre, juvā- juv-.
augēre, augē- aug-.
vincīre, vincī- vinc-.

2. By adding i, as capiō, Present Stem capi- (Verb Stem cap-).

3. By the insertion of n (m before labial-mutes) before the final consonant of the Verb Stem; as, fundō (Stem fud-), rumpō (Stem rup-).

4. By appending -n to the Verb Stem; as, -

cern-ō pell-ō (for pel-nō).

5. By appending t to the Verb Stem; as, -

flect-ō.

6. By appending sc to the Verb Stem; as, -

crēsc-ō. scīsc-ō.

7. By Reduplication, that is, by prefixing the initial consonant of the Verb Stem with i; as, -

gi-gn-ō (root gen-), si-st-ō (root sta-).

Formation of the Perfect Stem.

118. The Perfect Stem is formed from the Verb Stem -

1. By adding v (in case of Vowel Stems); as, -

amāv-ī, dēlēv-ī, audīv-ī.

2. By adding u (in case of some Consonant Stems); as, -

strepu-ī, genu-ī, alu-ī.

3. By adding s (in case of most Consonant Stems); as, -

carp-ō, Perfect carps-ī.
scrīb-ō, " scrīps-ī (for scrīb-sī).
rīd-eō, " rīs-ī (for rīd-sī).
sent-iō, " sēns-ī (for sent-sī).
dīc-ō, " dīx-ī (i.e. dīc-sī).

a. Note that before the ending -sī a Dental Mute (t, d) is lost; a Guttural Mute (c, g) unites with s to form x; while the Labial b is changed to p.

4. Without addition. Of this formation there are three types: -

a) The Verb Stem is reduplicated by prefixing the initial consonant with the following vowel or e; as, -

currō, Perfect cu-currī.
poscō, " po-poscī.
pellō, " pe-pulī.

NOTE 1. - Compounds, with the exception of , stō, sistō, discō, poscō, omit the reduplication. Thus: com-pulī, but re-poposcī.

NOTE 2. - Verbs beginning with sp or st retain both consonants in the reduplication, but drop s from the stem; as, spondeō, spo-pondī; stō, stetī.

b) The short vowel of the Verb Stem is lengthened; as, legō, lēgī; agō, ēgī. Note that ă by this process becomes ē.

c) The vowel of the Verb Stem is unchanged; as, vertō, vertī; minuō, minuī.

Formation of the Participial Stem.

119. The Perfect Passive Participle, from which the Participial Stem is derived by dropping -us, is formed: -

1. By adding -tus (sometimes to the Present Stem, sometimes to the Verb Stem); as, -

amā-re, Participle amā-tus.
dēlē-re, " dēlē-tus,
audī-re, " audī-tus,
leg-ere, " lēc-tus,
scrīb-ere, " scrīp-tus,
sentī-re, " sēn-sus (for sent-tus).
caed-ere, " cae-sus (for caed-tus).

a. Note that g, before t, becomes c (see § 8, 5); b becomes p; while dt or tt becomes ss, which is then often simplified to s (§ 8, 2).

2. After the analogy of Participles like sēnsus and caesus, where -sus arises by phonetic change, -sus for -tus is added to other Verb Stems; as, -

lāb-ī, Participle lāp-sus.
fīg-ere, " fī-xus.

a. The same consonant changes occur in appending this ending -sus to the stem as in the case of the Perfect ending -si (see § 118, 3, a).

3. A few Verbs form the Participle in -ĭtus; as, -

domā-re, dom-ĭtus.
monē-re, mon-ĭtus.

4. The Future Active Participle is usually identical in its stem with the Perfect Passive Participle; as, amā-tus, amātūrus; moni-tus, monitūrus. But -

juvā-re, Perf. Partic. jūtus, has Fut. Act. Partic. juvātūrus.[40]
lavā-re, " lautus, " lavātūrus.
par-ere, " partus, " paritūrus.
ru-ere, " rutus, " ruitūrus.
secă-re, " sectus, " secātūrus.
fru-ĭ, " frūctus, " fruitūrus.
mor-ī, " mortuus, " moritūrus.
orī-rī, " ortus, " oritūrus.
