The spelling of the word "twicer" can be confusing because of its silent "c." The IPA phonetic transcription for "twicer" is /ˈtwaɪsər/. The first syllable "twi" is pronounced like "twice" with a long "i" sound. The second syllable "cer" sounds like "sir" with a soft "s" sound. The silent "c" in "twicer" is a remnant of its Old English origin where the word was spelled as "twicer" or "twicerre." Today, the word refers to someone who does something twice or a betting strategy in gambling.
