What is the plural form of roof - roofs or rooves?
1. The plural of roof is roofs or rooves. "Rooves"
is an older form of the word and rarely used these days. Australian
children right up to the 1980s, for example, were brought up with
the word "rooves" rather than roofs, and it is still an accepted
form in Australia today (though uncommon). Also, despite New
Zealand English developing from UK English, it should be noted that
in NZ, the plural of roof is rooves, in both its written and
2. The accepted plural is "roofs". The Oxford English Dictionary
lists "rooves" as an alternate, one of several outdated spellings
used in the UK, and in New England as late as the 19th century.
