Prefixes and suffixes
 

hello

in every language there are prefixes and suffixes, eg in english -ly means adverb and in spanish -mente means adverb, pre- means repeat, -ic means adjective, etc

is there a complete reference list of these?

thanks

¡Pregunta bienísima! Espero que alguna lo repuesta

I was able to find a few websites that listed a number of suffixes and prefixes. The search I used was 'Spanish suffixes prefixes'. I don't know if there is any one place that contains a comprehensive list.

Sí, encuentro una buena lista.

¿Es "miento" un sufijo?

Nacimiento

Sí. Esto sirve para convertir un verbo en un sustantivo. Hay un sufijo equivalente en el inglés: -ment
to establish -> establishment

gracias, yo no lo veía en mi lista:)

what does the su- prefix mean? (poner, suponer)

Both su- and sub- mean under/underneath.

thanks
and sur- ?

It means over, above, beyond and upon. The Spanish prefix super- is probably a better match for the given definitions.

Other than those meanings, it can also mean the compass point sur. It is used to form some compound words, like Suramérica (also spelled Sudamérica) and Suráfrica.
sureste = southeast
suroeste = southwest
sureño = southern
