Meaning of -ARD in English
-ard BrE AmE əd, ɑːd AmE ə rd, ɑːrd —In well-known words this ending is əd AmE ə rd ( ˈ standard, ˈ custard, ˈ wizard, ˈ Edward). In less familiar words ɑːd AmE ɑːrd is an alternative or sometimes the only pronunciation, often through the influence of the spelling ( ˈ bollard, ˈ mansard). The suffix -ward(s) is usually wəd(z) AmE w ə rd(z) , but -yard is jɑːd AmE \ jɑːrd except usually in ˈ vineyard.
