La tercera persona del singular en los verbos regulares en inglés generalmente llevan el sufijo ‘s’. Este sufijo se añade al final de la forma infinitiva del verbo: eat = eats,write-writes.
Si el verbo termina en un sonido sibilante como ‘s’, ‘z’, ‘sh’, ‘ch’ que no esté seguido de una ‘e’ muda, se le añade el sufijo ‘-es’: rush – rushes. Teach- teaches.
Si el verbotermina en una consonante más ‘y’, la ‘y’ cambia a ‘I’ y se añade ‘-es’: cry – cries, fry- fries.
Los verbos que acaban en ‘o’ suelen añadir ‘-es’: go – goes, do - does
Hay verbos que nunca toman la‘s’ para la tercera persona, por ejemplo can, may, must.
