masseur

This term specifically denotes a male practitioner of massage. While the profession is gender-neutral in modern clinical settings, this word maintains a gendered distinction from the female counterpart, masseuse. It carries a connotation of professional therapeutic care, often associated with sports medicine, physical therapy, or luxury spa environments.

Because it refers to a specific professional role, it functions as a standard countable noun. It does not possess any irregular pluralization or restrictive countability constraints that would require partitive constructions.
