The spelling of the word "sparer" may seem peculiar at first glance, but it follows a common pattern in English. In IPA phonetic transcription, it is pronounced /ˈspɛərər/. As with many words in English, the spelling does not always correspond directly with the pronunciation. In this case, the "a" in "sparer" is pronounced as a "schwa" sound, which is common in unstressed syllables. The "-er" ending indicates a person who does something, as in "a baker" or "a runner." So, a "sparer" might be someone who saves or conserves something.
