In this Hungarian lesson we will see how to express that someing is causing someone
to do something. We will turn "I read the book" into "I cause Ági to
read the book".
This effect can be as literal as the above, or can create words with a mode everyday
meaning. For example, saying, "I caused the baby to eat," is less comman than, "I
fed the baby," but the effect is the same (well, so long as you don't add "to the
lions" to the latter!).
 
The endings we apply are -at/et and -tat/tet.
These endings will turn "to do something" into "to make somebody do something".
The choice of endings is governed thus: generally, one-syllable stems get
the -at/et ending, and polysyllabic stems get the 
-tat/tet endings.
Of course, Hungarian vowel harmony then comes into play.
Some examples:
| 
mos wash mosat make somebody wash
 
hív call hívat make somebody call
 
olvas read olvastat make somebody read  | 
keres seek kerestet make somebody seek
 
öltöz|ik dress (oneself) öltöztet make somebody get dressed, to dress somebody  | 
 
     
Having added the causative ending, we continue to conjugate as normal based on subject and object.
The conjugation of the verb is based upon who is doing the making, not who is doing the action.
Later we will see how to show whom we are making. 
- mosatok  I make (somebody) wash  
- hívatsz you make (somebody) call
- olvastatnak they make (somebody) read
 
Lets have a look at some sentences with just a single direct object. Later we'll
see some examples with indirect objects.
- várom őt I await him (I wait for him)  
- váratom őt I make him wait
 
 
- ismerem őt I know him 
- ismertetem őt I make him be
known - I introduce him 
- ismertettem őt I introduced
him (past tense)
 
 
- kitisztít clean 
- kitisztíttattam a ingomat I had
my shirt cleaned
 
 
- csinál make 
- kellett csináltatni egy speciális fényképet
I needed to have a special photo made
 
 
 
The above shows that we made something happen, and we saw that we made it happen
to a grammatical object. Now we need to show who will be doing the deed.
 We use the  Hungarian instrumental case (-val/vel)
to show who is doing the action.
- Daniel a Ágival keresteti a kutyát Daniel makes Ági seek the dog 
- Ági Daniellel hívat egy taxit 
Ági makes Daniel call a taxi 
- Ági velem olvastatta a könyvet 
Ági made me read the book 
- hozatok Ágival bort 
I   make Ági bring wine (I'll have Ági bring wine) 
- hozatsz Ágival  bort 
you   make Ági bring wine 
- hozatnak Ágival  bort 
they  make Ági bring wine 
- Daniel Ágival írat  levelet 
Daniel makes Ági write a letter 
This is a great example, because it demonstrates
that the teacher is doing the making, we are the ones made to do it,
it was done in the past, and to a definite object.
a tanár olvastatta velünk a könyvet the teacher made us read the book
Construction:
- a tanár subject
- olvas reading 
- -tat- makes do
- -ta past definite, 3rd person sngular (agrees with "a teacher" and "the book")
- velünk we are made to do the reading
- a könyvet definite object, in 
accusative  case 
 
We may even want to say that we could cause someone to do something. Just
like when we make the regular 
could mood, we can also apply the same rule here.
The construction is:
stem + causative + permission/potential + conditional = could make
do something
- Daniellel hív + at + hat + nál egy taxit Daniel{instrumental} call + cause + may + conditional{you} 
- Daniellel hívathatnál egy taxit 
you could have Daniel call a taxi
