dec·ade
\ˈdeˌkād also deˈkād or də̇ˈkād or ˈdekə̇d; the last is most frequent in the sense “division of a rosary” and many who first learned the word in this sense use this pronunciation for all senses; since d and t are identically pronounced in certain intervocalic environments by most U S speakers, some who first learn the word aurally in a context such as “decade of the rosary” originally apprehend the last consonant letter as t and pronounce the word in all its occurrences as if the last consonant letter were t, making the plural for instance ˈdekə̇ts\ noun
(-s)
