The very common word ending <ary> is often pronounced simply as ri. Here are examples of words with this ending:
boundary necessary primary secondary secretary
The same is true of the ending <ory>. Examples:
category directory history memory preparatory victory
Of course this is not true if the first syllable of the ending is stressed. <ary> is then pronounced eəri, as in:
chary Mary scary unwary
and <ory> is pronounced ɔːri as in:
gory story Tory
