welcome back to Rocket Italian Forum.
"N'è" is the union of the pronoun ne +the verb "è" (is).
The pronoun "ne" can be translated in English in different ways depending on the sentence you have.
Generally it means "about him/her/them/it", "from that", "of it/them", "any", "some", "any", "other".
I know it could sound a little bit confusing so I write here some examples:
-Io amo i cani. Ne ho sempre avuti tanti. (I love dogs. I always have got many of them)
-Carlo ne vuole tre (Carlo want three of them)
-Non ce ne sono più (There aren't any more)
Hope to have been helpful!
Please let me know if you need any further information.
All the best for your Italian learning!
