Some linguistic declension forms are found in many languages:
- Singular / Plural
- Past, Present, Future
- Indication, Condition, Imperation
- Case: Nominative, Accusative, Dative etc.
Is there a more or less established set of graphic icons for these forms?
For Gender and Number it's quite easy:
- Gender: ♀ and ♂
- Singular and Plural: 👤 and 👥
However, for time, mode and case, it gets quite difficult to come up with something that a majority of people might understand. That's why I'm looking for an established set of icons. If there is not any, perhaps there is a well-known book like a thesaurus that uses such a set of icons?
