When there are several plural nouns in a sequence, do they all take the plural form or does only the last noun take the plural e.g.,
The application is a precious instrument full of information, advices, curiosities and suggestions.
The words "information" and "advice" cannot be pluralized. The words "curiosity" and "suggestion" can be pluralized but take on different meaning in plural than in singular.
So, no, the nouns do not have to be all singular or all plural.
