Correct spelling, explanation: the correct form is applied. This is because the verb apply follows a common spelling rule for regular verbs in English: when a verb ends with a consonant followed by a -y, you change the -y to an -i and add ed to form the past tense. Thus, apply becomes applied, not applyed. Applyed would be a violation of the consonant + y rule. It doesn’t fit standard English spelling conventions, which is why it looks unusual or incorrect to native speakers.
Definition of applied:
Adjective, relating to a subject of study, especially a science, that has a practical use

Incorrect spelling, explanation: you can’t spell applied as applyed due to specific spelling rules in English related to how we form the past tense of regular verbs that end with -y. In English, when a verb ends with a consonant followed by -y, you change the -y to -i before adding the past tense suffix -ed. Thus, apply becomes applied, not applyed. The form applyed breaks this well-established rule, which is why it’s not correct.
