Because that is how the past is formed for regular verbs. Usually to form the past of regular verb we add -ed.
walk / walked talk / talked
When the verb ends in -y then "y changes to i then add -ed" or as you say "y changes to ied". eg
marry / married hurry / hurried
First, look in a dictionary or similar reference of adequate size to determine whether the verb has an irregular past participle shown. (There are lists of such verbs in Cassell's English-French and English-German dictionaries, and probably in others.) If the verb has an irregular past participle, use that.Otherwise, the verb is regular, and its past participlecan be formed by following these rules, in order:(1) If the third person singular present indicative form of the verb ends in the letter "e", add "d" to the third person singular present indicative spelling to obtain the past participle.(2) If the third person singular present indicative form of the verb ends in the letter "y" and the letter "y" is not immediately preceded by a vowel, change the "y" in the third person singular present indicative spelling to "ied" obtain the past participle.(3) In all other instances, add "ed" to the third person singular present indicative spelling to obtain the past participle. It may be necessary also to double any final consonant of the third person singular present indicative spelling to obtain the properly spelled past participle. This is particularly likely if the final consonant is preceded by a single vowel in the third person singular present indicative spelling. If not sure of whether to double such a consonant or not, look in a reference!.
Some examples of words where you drop the "y" and add "ied" are "cry" to "cried," "try" to "tried," and "copy" to "copied."
The word "study" has two syllables. It is pronounced as /ˈstʌd.i/.
Suffixes for 'worry' are: -ing for worrying -ied for worried -ies for worries -wart for worrywart
Buried has two syllables. Bur-ied
In general, most verbs ending with "y" will have a past form ending with "ied".Eg. SaveHe tried and failed so he cried. The bird flied and she lied.
the suffix -ied is used to make a verb past tense such as carry to carried, bury to buried etc.
A regular verb is a verb whose past tense is made by adding -ed. eg walk - walked, continue - continued, play - played An irregular verb is a verb that has a new word for the past. eg run - ran. see - saw, buy - bought.
