Editing English plurals (section)

==== Other voiced phonemes ====
For a singular noun ending on a non-sibilant voiced consonant, the plural adds {{IPAc-en|z}} (a voiced sibilant) and the spelling adds ''-s'':
{{block indent|{{wikitable
|-
|girl||girls||{{IPAc-en|ɡ|ɝ|l|z}}
|-
|chair||chairs||{{IPAc-en|tʃ|ɛər|z}}
}}}}

In English, all vowels are voiced. Nouns ending in a vowel sound similarly add {{IPAc-en|z}} to form the plural. The spelling usually adds ''-s'', but certain instances (detailed below) may add ''-es'' instead:
{{block indent|{{wikitable
|boy||boys||{{IPA|/bɔɪ'''z'''/}}
}}}}

=====Plurals of nouns in ''-o'' preceded by a consonant=====
Singular nouns ending in ''o'' preceded by a [[consonant]] in many cases spell the plural by adding ''-es'' (pronounced {{IPAc-en|z}}):

{{block indent|{{wikitable
|hero||heroes||{{IPAc-en|'|h|i|ɹ|oʊ|z}}
|-
|potato||potatoes||{{IPAc-en|p|ə|'|t|eɪ|t|oʊ|z}}
|-
|volcano||volcanoes ''or'' volcanos||{{IPAc-en|v|ɒ|l|'|k|eɪ|n|oʊ|z}}
|-
|echo||echoes
}}}}

However, many nouns of foreign origin, including almost all [[Italian language|Italian]] loanwords, add only ''-s'':
{{block indent|{{wikitable
|canto||cantos
|-
|hetero||heteros
|-
|photo||photos
|-
|zero||zeros (''or'' zeroes)
|-
|piano||pianos
|-
|portico||porticos
|-
|pro||pros
|-
|quarto ''(paper size)''||quartos
|-
|kimono||kimonos
