Un sufix és una lletra o un grup de lletres que s’afegeixen al final d’una paraula per a formar una nova paraula o per a canviar la funció gramatical de la paraula. Per exemple, en els sufixos en anglès, el verb dance es converteix en nom en afegir el sufix -er (dancer). De la mateixa forma, dance es pot convertir en adjectiu afegint el sufix –able (danceable).

Hi ha dues classes de sufixos en anglès:

  1. Inflectional (gramaticalment): per exemple, canviant de singular a plural (dog / dogs) o canviant de temps present a passat (walk/ walked). En aquest cas, el significat bàsic de la paraula no varia.
  2. Derivational. Afegint el sufix el significat de la forma original canvia. (Teach / Teacher = Ensenyar).

Ara mirarem detalladament cada tipus de sufix en anglès.


Com hem dit abans, en aquests casos no es canvia el significat original de la paraula. Hi ha molt pocs tipus, però són molt freqüents.

Suffix Grammatical change Original word Suffixed word



plural Dog






-en plural (irregular) Ox Oxen
-s 3rd person singular present Like He likes
-ed past tense & past participle work He worked

He has worked

-en past participle (irregular) Eat He has eaten
-ing continuous / progressive Sleep He is sleeping
-er comparative Big Bigger
-est superlative Big The biggest
-n’t negative contraction Do Don’t


En aquest cas, afegint un sufix en anglès el significat varia, encara que aquest canvi de significat està relacionat amb l’antic significat. Podem afegir més d’un sufix, per exemple:

derive (verb) + ation → derivation (noun) + al → derivational (adjective)

Guia ortogràfica per als sufixos en anglès

Regla 1

Afegint un sufixe consonàntic directament a la paraula base.

Wonder + ful = wonderful

Regla 2

Comprova la paraula base abans d’agregar un sufix amb vocal.

Si la paraula base acaba amb dues consonants, simplement afegeix el sufix.

Teach + er = teacher

Si la paraula base té només 1 síl·laba, una única vocal i una consonant final, llavors dobla la consonant final abans d’afegir el sufix.

Big + er = bigger

Si la paraula base acaba amb una E silenciosa, elimina la E abans d’afegir el sufixe amb vocal.

Love + ed = loved

Regla 3

Si la paraula base acaba amb una I, canvia la Y per una I abans d’afegir el sufix.

Heavy + ness = heaviness

Beauty + ful = beautiful

Existeixen més regles però només s’apliquen a un petit nombre de paraules. I com en totes les regles, hi ha excepcions.  Si vols continuar ampliant el teu coneixement, no deixis de visitar la nostra notícia referent als prefixos en anglès.
