Spanish Suffixes, Prefixes and Diminutives
Spanish builds new words by attaching endings and prefixes to existing roots, which means learning one word often gives you several. These building blocks are highly regular, so once you know the common suffixes and prefixes you can both understand and form words you have never seen. This page covers diminutives and augmentatives, the suffixes that create adverbs and nouns, and the prefixes that change meaning.
Diminutives and Augmentatives
Diminutive endings signal small size, youth or affection. The most common are -ito and -ita, which attach to nouns and adjectives:
- casa (house) → casita (little house)
- perro (dog) → perrito (puppy)
- momento (moment) → momentito (just a moment)
The endings -illo and -ico work the same way in different regions. Diminutives often add warmth rather than literal smallness, so abuelita is an affectionate word for grandmother, not a small one.
Augmentative endings do the opposite, signalling large size or force. The most common are -ón, -azo and -ote:
- libro (book) → librote (big book)
- golpe (blow) → golpazo (heavy blow)
- hombre (man) → hombrón (large man)
Suffixes That Map Onto English
Several Spanish suffixes correspond directly to English ones, which makes both recognition and word-building predictable.
| Spanish suffix | Function | English equivalent | Example |
|---|---|---|---|
| -mente | forms adverbs | -ly | rápido → rápidamente |
| -ción | forms nouns | -tion | crear → creación |
| -dad or -tad | forms nouns | -ty | real → realidad |
| -eza | forms nouns | -ness | triste → tristeza |
| -miento | forms nouns | -ment | mover → movimiento |
| -oso | forms adjectives | -ous | fama → famoso |
Prefixes That Change Meaning
Prefixes attach to the front of a word and shift its meaning in familiar ways:
- des- reverses an action: hacer (to do) → deshacer (to undo)
- in- and im- negate: posible (possible) → imposible (impossible)
- re- marks repetition or intensity: hacer → rehacer (to redo)
- pre- means before: ver (to see) → prever (to foresee)
- anti- means against: cuerpo (body) → anticuerpo (antibody)
Because these prefixes carry the same sense as their English counterparts, they are easy to apply and to decode.

A diminutive is an ending such as -ito or -ita that signals small size or affection, as in casita (little house) or perrito (puppy). Spanish uses diminutives far more than English, often to sound warm or friendly rather than to mean literally small.
The suffix -mente turns an adjective into an adverb, exactly as -ly does in English. Rápido (quick) becomes rápidamente (quickly), and the ending is added to the feminine form of the adjective where one exists.
Word formation lets you turn one known root into a family of related words, so learning crear (to create) also gives you creación (creation) and creativo (creative). Recognising suffixes and prefixes multiplies vocabulary without memorising each word separately.
