The spelling of the word "wooder" may raise some eyebrows for those unfamiliar with the regional dialect of Philadelphia. This word refers to a type of water ice commonly found in the area, similar to Italian ice. The unusual spelling can be explained through its phonetic transcription: /ˈwʊdər/. The "oo" sound represents the "u" sound in "book," while the "er" at the end is pronounced as the "uh" sound in "sofa." So, "wooder" essentially spells out the way it's pronounced in the Philly dialect.
