11. A verb is reflexive when the subject
and the object are the same.
Example:
I wash myself.
subject: I
verb: wash
object: myself
Since the subject and object are the
same, the verb is reflexive. The purpose of the reflexive object
pronouns is to show that the action of
When a verb is reflexive, the the verb remains with the subject.
infinitive ends in "se.“ Example:
Example: Juan se lava la cara.
lavar Juan washes his face. (reflexive)
to wash (non-reflexive) Juan lava su carro. (non-reflexive)
lavarse Juan washes his car.
to wash oneself (reflexive) Note: When referring to body parts, use

13. The vowels a, e, and o are strong in Spanish. They always form their own syllable wherever they appear. The
vowels u and i are weak, and only form their own syllable when they are separate from other vowels. When a
weak vowel is next to a strong vowel or another weak vowel, they AUTOMATICALLY form a diphthong,
that is, just one syllable.
Strong vowels (a, e, o) always form their own syllables:
o - tor - gar (3)
Weak vowels (i, u) form a their own syllable if they are "surrounded" by
consonants:
tri - bu (2)
Otherwise, weak vowels form a diphthong with the strong vowel that is
next to them:
lue - go (2

14. Verbs that end
• Verbs that end in -ger and -gir in a consonant
change the g to j in the yo + -cer or -cir

• Verbs that end in -guir change convencéis
the gu to g in the yo form convencen
Verbs that end

consigues
e, and a.

15. Hacer expressions
• Hace + time + que + present tense form of the verb
• Hace un año que estudio español.
I have been studying Spanish for one year.
• Hace dos años que ellas estudian inglés.
They have been studying English for two years.
•
Another way to use the verb "hacer" to express how long something
has been taking place is to use the following formula:
• Present tense form of the verb + desde hace + time
• Estudio español desde hace un año.
I have been studying Spanish for one year.
So, when it comes to using the verb "hacer" to express the length of
time an action has been taking place, there are two ways to say the
same thing:
• Estudio español desde hace un año.
Hace un año que estudio español.
I have been studying Spanish for one year.

27. SUPERLATIVES
• There are two types of superlative: relative and absolute.
• Relative: John is the smartest boy in the class.
Absolute: John is very smart.
The relative superlative describes a noun within the context of some larger group.
• John is the smartest boy in the class.
Mary is the youngest person in the room.
Of the three, Moe is the meanest.
•
The absolute superlative does not describe the noun in the context of a larger group.
• John is very smart.
The book is extremely expensive.
The food is indescribably tasty.
The absolute superlative for adjectives has three possible forms.
• muy + adjective
sumamente + adjective
adjective + ísimo (-a, -os, -as)

28. Comparatives
• If two things are not equal, they are unequal.
• We are not the same height.
You are taller than I.
• The two items do not cost the same.

•
In Spanish, inequality is expressed by using one of the following formulae:
• más (menos) + adjective + que
más (menos) + adverb + que
más (menos) + noun + que
• Here are some examples:
• Tú eres más alto que yo. You are taller than I. Mónica habla más lentamente que
Carmen. Monica speaks more slowly than Carmen. Tengo menos libros que
Arsenio. I have fewer books than Arsenio
•

29. FUTURE
The future tense is used to tell what "will" happen, or what "shall" happen.
• I will go to the beach next month.
I shall write the letter next week.
• But, the future tense is not used to express a willingness to do something. For this,
use the verb "querer."
• ¿Quieres ir a la tienda?
Will you go to the store?
• Regular verbs in the future tense are conjugated by adding the following endings
to the infinitive form of the verb: -é, -ás, -á, -emos, -éis, -án.
• hablaré
hablarás
hablará
hablaremos
hablaréis
hablarán
