The word "TOLLSESTER" is a combination of two words "toll" and "sister". It is spelled as /tɒlsɛstə/. The "toll" is spelled with a double "ll" and "sister" is spelled with an "s" instead of a "c" because it comes from the Old English "suster". The added "e" after "toll" is a silent letter and is added to indicate that the "o" in "toll" should be pronounced as a short sound. Together, the word means a sister who collects tolls or fees.
