Singular & Plural Nouns – By adding -s or changing -f into -ves (List)

Many English nouns form their plurals by simply adding -s, while a smaller group ending in -f or -fe often change that ending to -ves. Usage, however, isn’t uniform: some nouns allow both forms, with preferences varying by dialect, meaning, or tradition (think dwarfs/dwarves and hoofs/hooves). This list gathers common examples you can learn at a glance. When two plurals are shown, the first is the more frequent in general use; the alternative is acceptable, sometimes in technical senses. Always check context, especially with words like scarf or turf, where the -ves form may sound formal or British.
