RULE 1: The fourth principal part of
the verb is the perfect passive participle; it carries
a sense of past-tense action with it.
RULE 2: The perfect passive participle
+ a form of esse = the perfect passive system of the Latin
There are two especially important things to remember in the chapter.
The first is that the Latin perfect passive participle conveys a past-tense
connotation (-1 in time) and so, when combined with present-tense forms
of esse (+0), creates the perfect passive. The
second is that, with the introduction of the perfect passives, the Latin
verb may for the first time in your experience consist of more than one
A. Formation of the Perfect Passive System
The formula for creating perfect passive forms is simple: the perfect
passive participle + a form of sum. In practice, however, this
verb system poses certain difficulties for English speakers:
1. The Formation of the Perfect Passive in Latin and English.
In Latin, the sense of past tense is included in the participle,
not as in English in the form of the verb "to be." That is,
Latin says laudatus sum, literally "I am + having been
praised" (i.e. "I now exist in a state of having been praised
in the past"). Conversely, in English a past tense form of the
verb "to be" + the (present) passive participle creates the
perfect passive system: I have been + praised. English speakers
are innately attuned to hearing the tense of a multi-word verb form
in the verb "to be" and so when they hear a present form of
"to be," they naturally assume the verb is present. That is,
be careful not to make the mistake of misinterpreting laudatus sum
as "I am praised," when it is correctly
translated as "I have been praised" (because
the participle laudatus is perfect in tense).
From there, the rest of the tenses follow logically:
a. Pluperfect: the perfect passive participle (-1)
+ the imperfect of sum (-1) = pluperfect passive (-2);
b. Future Perfect: the perfect passive participle
(-1) + the future of sum (+1) = future perfect passive (+.5).
2. The Agreement of the Perfect Passive Participle with the
Subject. As an adjective, the perfect passive participle must
agree with a noun, even if that noun is not stated explicitly. Because
the verb is tied to the subject, the perfect passive participle will
refer to the subject and will therefore be in the nominative case. It
will also change its number and gender in accordance with the subject,
something you need to remember. That is, it's important to check the
number and gender of the perfect passive participle when you are creating
Latin perfect passive forms. On the other side of the issue, remember
too that, when you're reading Latin, the perfect passive participle
can be of great help in determining the subject of the sentence since
it shows the subject's number and gender.
3. Translating the Perfect Passive. As with other
verb forms, there are several English translations of perfect passive
forms: I have been praised, I have been being praised,
I was praised. Just like perfect active forms, perfect passive
forms show past action which has been completed and usually has some
sort of bearing on the present.

(n.) [versus qui, quae, quod];
4-5) the accusative and ablative feminine forms: quem and
quo [versus quam and quâ].
Note that the interrogative adjective is identical in form to the relative
pronoun but very different in use: the interrogative adjective is a modifier
used in the main sentence, whereas a relative pronoun introduces a subordinate
clause. It's usually translated as "what (man)?" or "which

studium: Means primarily "desire, eagerness,"
only secondarily "study." Students originally "desired"
learning and knowledge. As an abstract noun, studium can be used
as an ablative of manner.
certus: Means "certain" in the sense
of "without question," not "some" (which is quidam,
Chapter 26). Certus derives from the verb cerno ("separate"),
making it literally "separated, distinguished."
paro: The original sense of the verb was simply
"put, set; make ready" but, aided by its compound praeparo
(literally, "make ready in advance"), it took on the sense "prepare,"
hence "provide, furnish, get, obtain, buy." Remembering this
Latin word can help with the spelling of a particularly difficult English
word, separate (all too often wrongly spelled seperate);
separate means literally "put (-par-) apart (se-)."
