NOTE: In Spanish, there are two slang prefixes, requete - and super -, that are more intense than - re, but NOT as intense as superlative forms of adjectives. They mean practically the most. Furthermore, they can modify ONLY adjectives.

DISMINUTIVO/ DIMINUTIVE

Diminutives are used to express smallness or affection.

English has a few common diminutives, such as kitty, doggy, sonny, also some proper names have diminutive forms, such as Bobby, Vicky, etc. In Spanish, most nouns and adjectives have diminutive forms, which is the equivalent to modifying a word with little. The most common diminutive suffixes are the following:

	SINGULAR	PLURAL
MASCULINE	-ito, -cito	-itos, -citos
FEMININE	-ita,-cita	-itas, -citas

The following diminutive suffixes are less commonly used:

	SINGULAR	PLURAL
MASCULINE	-illo	-illos
FEMININE	-illa	-illas

1. Generally, when words end in -a, -o or -te, the vowel is dropped and -ito(s) or -ita(s) is added. For the other words -cito(s), -cita(s) are used. However, these are NOT rules. They are only guides because there are many variations.
