In Spanish, how are sentences formed (adjectives, nouns, and verbs)?

I have noticed that some adjectives come before the noun and some come after.

I don't know about Spanish but in Portuguese

Um homem grande.... a big man.

Um grande homem....a great man.

If I remember correctly (I might not)
typically in Spanish an adjective follows the noun it modifies
UNLESS you want to emphasize the adjective.
