does gótico keep the accent when made plural?
if you want to make gótico plural, would it be góticos or goticos, without the accent.
Góticos with accent
I would say, as a general rule, nouns and adjectives with accents keep their accents in the plural -- unless the accent becomes redundant in the plural.
Let's consider gótico. If we pluralize it and remove the accent we have goticos, which would carry stress on the i, therefore the stress mark should remain on the o. But, now let's consider opción. If we pluralize it and remove the accent we get opciones. In plural form, without the accent, the second o gets the stress anyway; therefore, we can drop the accent mark.
Another way to put it: if the accent mark is on the final syllable in the singular AND if making the word plural adds another syllable, we should (usually) drop the accent mark. In (almost) all other cases, we should keep it.
Yet another way to look at it: the same syllable stressed in the singular should be stressed in the plural. If that syllable would receive the stress in the plural without the mark, then drop it. Otherwise, keep it.
