The correct spelling of the word for the small patches of melanin on skin is "freckle." The incorrect spelling, "freckl," lacks the crucial "-le" ending. In phonetic terms, "freckle" is pronounced /ˈfrɛk(ə)l/ with the stress on the first syllable and a schwa sound in the middle. The "le" ending is pronounced with a dark L sound /l/ and a syllabic schwa /əl/, making the phonetic transcription for freckle end with /k(ə)l/. It's always important to spell words correctly to avoid confusion in communication.
