“Tardies” is the correct plural spelling of “tardy,” while “tardys” is incorrect according to standard English spelling rules.
During a school meeting, a teacher reviewed the attendance report and mentioned that several students had multiple tardies that month. A parent reading the report later wondered whether the word should actually be spelled tardys instead. This small spelling question appears frequently in school settings.
Many people search for “tardies or tardys” because English plural rules can sometimes feel confusing. When a word ends in “y,” the plural form does not always follow the simple rule of adding “s.” Instead, the spelling often changes depending on the letter before the y.
