In Latin the cases are arranged (mostly) 1 nominative, 2 genitive, 3 dative, 4 accusative, 5 ablative. If I want to indicate the function of a word in a sentence I simply use the numbers after the noun, irrelevant of how these functions are called in Latin, German, French or English. — rogermue 1 hour ago

Would you consider superscripting your tags and replacing the numbers with something a shade more transparent? Our learners are unlikely to have studied Latin, but NOM, GEN, DAT, ACC, ABL are at least in contemporary linguistic use, while your numbers are meaningless outside the western tradition of Latin pedagogy. OE, for instance, usually uses the sequence NOM, ACC, GEN, DAT. Comments won't superscript, but in Answers, you can put you<sup>ACC</sup>and it will display just dandy. — StoneyB 1 hour ago
