Ningún, Ninguna

Question

Not clear on what this means:"You can only use the singular forms ningún and ninguna at the beginning of a sentence if you are not using the double negative "no...ningún/ninguna".Can you please provide the latter  "no...ningún" with plural examples?

Hola Thalia C.
The important distinction here is the position of ninguno/ninguna in the sentence.
When ninguno/ninguna comes before the verb, you don't need no:
Ningún estudiante vino. – No students came.
Ninguna de mis amigas llamó. – None of my friends called.
However, when it comes after the verb, you need no before the verb:
No vino ningún estudiante. – No students came.
No llamó ninguna de mis amigas. – None of my friends called.
Notice that ningún/ninguna remains singular even when the English translation refers to several people.
I hope this makes the distinction clearer!
Un saludo
