The spelling of "deekies" may seem unusual, but it can be explained through phonetics. The word is pronounced /diːkiːz/, with the emphasis on the first syllable. The "ee" sound in the word is represented by the double "e" in the spelling. The ending "-ies" reflects the plural form of the word, similar to how "cookies" is the plural of "cookie". While the spelling may be unconventional, it accurately represents the sound of the word.
