So, how do we make a passive periphrastic?
3
As usual, we start with the Infinitive.
4
For -are, -ere, and regular -ere verbs,
simply remove the re and add ndus -a
-um. amandus, habendus, agendus
5
If the verb is third io or fourth (-ire) take
off the entire infinitive ending and add iendus
-a -um. capiendus, audiendus
6
This form is known as the future passive
participle or the GERUNDIVE!
7
We combine this gerundive with a form of
esse to make the passive periphrastic which
indicates necessity!
8
Notice that the ending on the gerundive
is -ndus, -a -um. This indicates that it is
treated like a first and second declension
adjective such as magnus, -a. -um.
9
Well, youre probably thinking, thats just
great, but how am I supposed to know which of the
thirty possible endings to use on the darn thing?
10
Well, lets look at just what
you are trying to express.
11
Lets take this expression and turn it into
Latin I must ask the girl. The verb will become
my gerundive. The object of the verb will become
my new subject. My current subject will move to
the dative of agent.
12

The subject
My old object becomes my new subject, so it will
be girl Puella I am now rethinking the
sentences as The girl must be asked by me
13
The verb
rogare would become rogandus -a -um
Since I am rethinking the sentence as The girl
must be asked by me, asked is sort of like an
adjective describing the girl. What must she be?
Asked!
14
Well now, since adjectives need to be the same
gender, case. and number as the nouns they
modify, and since puella is fem. and nom. and
sing., then rogandus would become roganda! So
now we have Puella roganda
15
Hey, dont we need a form of esse?
16
You bet! Since our subject is puella, we use
est! (If it were puellae, wed use sunt.
Get it?)
17
So now we have Puella roganda est. Now we take
our old subject
I and we change it into something called the
dative of agent. Instead of use a, ab and the
ablative, we put it in the dative mihi. a
dative of agent acts just like an ablative of
agent, only it doesnt use a preposition, and
its not in the ablative(!)
18
So, to make a long story, welljust as long here
are the steps 1. Rethink the sentence to make
your old object your new subject. 2. Create a
gerundive for your verb and give it an ending
that agrees with your new subject 3. Add a form
of esse that agrees with your new subject. 4.
Change your old subject into the dative.

Now, wasn't that easy!
