The spelling of the word "pleuroscopes" can be tricky. It is pronounced /plʊrəskoʊps/ and the IPA transcription helps explain the spelling. The "pleu" in the beginning reflects the Greek root word "pleura", which means rib or side. The "o" in between the "r" and "s" is the schwa sound, and the "scope" at the end refers to a device used for examining a body cavity or internal organ. Therefore, "pleuroscopes" would mean instruments used to examine the ribs or sides of a body.
