Morphology
Acanthurus + chirurgus
This is a taxonomic binomial: the first element 'Acanthurus' clearly identifies the genus (a type of spiny reef fish), so that part transparently signals a fish species. The second element 'chirurgus' is a Latin/Greek-derived epithet (related to 'surgeon') and is not a standard English word, so its contribution to meaning depends on knowledge of classical roots and taxonomic naming conventions. Because the overall meaning (a species of surgeonfish) is partly derivable but requires non‑everyday/Latin knowledge, it is only partially transparent to learners.
Etymology
Acanthurus chirurgus gets its name from a sharp tail spine that looks like a small knife a surgeon would use. Because of that cutting spine, people call it 'surgeonfish' or 'doctorfish', so the name reminds us of a doctor.
