This should be people are walking on the rooves
Roofs is the plural of roof in all varieties of English. Rooves is an old secondary form, and it still appears occasionally by analogy with other irregular plurals such as hooves, but it is not common enough to be considered standard.
Should definitely be accepted though.
No, it shouldn't. Hulk is right. It's not standard. I've never seen it spelled that way.
I'm English and I've lived in England my entire life. A lot of northerners (including myself) do and have always spelled it "rooves".
BetsyLowe, try looking in a dictionary.
If it's used, it should be accepted.
Even if it isn't used, it should still be accepted, since it's a perfectly logical plural, and some non-native speakers might use it. So it's good to not be marked as wrong just for using "rooves".
Should it not be "are walking"?
Rooves or Roofs - both are acceptable in English.
I am an English speaker. I have to hear anyone say rooves.
plural noun: rooves
I was marked incorrect presumably because of US English?
