Spondylarthrocace is a medical term, which refers to the destruction of joints connecting the vertebrae. Its spelling might seem daunting, but it’s broken down phonetically: spon-dyl-ar-thro-cace. The first syllable, spon, is pronounced like the beginning of the word sponge. The second syllable, dyl, sounds like the beginning of the name Dylan. Arthro is pronounced ar-thro, with the 'th' sound like in the word 'thin'. Finally, cace is pronounced like the word case. When broken down in this way, spelling spondylarthrocace becomes a bit more accessible to even the most inexperienced orthographer.
