The document discusses perfect infinitives in English and Spanish. In English, the perfect infinitive is formed with "to have" and the past participle, expressing that the action happened in the past. Spanish forms it similarly with "haber" and the past participle. The perfect infinitive can follow certain verbs in both languages. It also discusses the differences between the Spanish verbs "ser" and "estar", noting that "estar" expresses a state of being while "ser" can imply a permanent characteristic when used with adjectives or a caused action when used with a past participle.

2. The Infinitive
• In English and Spanish, the infinitive verb form
often appears after other verbs.
• We sometimes say it “finishes” the verb.
– Examples: I want to go to the party.
– Quieroir a la fiesta.

3. The Perfect Infinitive: English
• In English, we form the perfect infinitive with
the infinitive of the verb “to have” and the
past participle. Ex: to have known
• We use this to express the idea that the verbal
activity conveyed by the infinitive happened in
the past.

4. More on the Perfect Infinitive
• The perfect infinitive phrase can be used as a
type of subject of a verb or it can occur behind
a verb.
• The verb in front of the infinitive can be in
either past or present tense.

5. Examples
– To have known about the scandal was not
fortuitous.
– He claims to have known about this scandal.
(claim is current; knowledge was in the past)
– He claimed to have known about this scandal.
– (claim was in the past; knowledge was in the past
before the claim)
• The perfect infinitive is NOT used with every
verb in English – it is only used with those that
can take an infinitive.

6. Nuances of the Perfect Infinitive
• Consider the nuances of these sentences:
1. I wanted to go to the party.
2. I wanted to have gone to the party.
3. He claimed to be her long lost husband.
4. He claimed to have been her long lost
husband.

7. Spanish Perfect Infinitives
• The Spanish Perfect Infinitive is somewhat like
that in English.
• It is formed with the verb “haber” and the
past participle (ido/ado) form of the verb.
Example: habersabido (to have known).

8. Example
• It is used in various places in the sentence, but
generally comes after certain (not all) other
verbs, which can be in the past or present.
• Élafirmahabersabidolos hechos. (He claims to
have known the facts).
• Élafirmóhabersabido los hechos. (He claimed
to have known the facts).

9. Translation Warning
• Sometimes, the translation of a perfect
infinitive in Spanish works better as a
translated infinitive or even a gerund in
English.
• Yoniegohaberhechoesecrimen.
• I deny having done that crime.

10. More on Ser/Estar
• As previously mentioned, Spanish has two forms
of the verb “to be” --- ser and estar.
• These two verbs generally are used in different
ways.
• There is a great deal of overlap in the way these
verbs can be translated (as forms of the English
“to be”).
• There are times when there are significant
differences in they way they are used in Spanish -
-- and thus translated in English.

11. Morir
• The Spanish verb for “to die” is “morir.”
• The past participle is “muerto.”
• When used with estar the construction means
“to be dead.”
• Example: Mimadreestámuerta. (My mother
is dead).

12. Examples
• When used with a form of ser the construction
means to have been killed (meaning
assassinated --- not just an accident).
• Nicole Brown
SimpsonhabíasidomuertaporsuesposoOJ
Simpson. (Nicole Brown Simpson had been
killed by her husband OJ Simpson).
• Nicole Brown Simpsonestámuerta. (Nicole
Brown Simpson is dead).
