Final answer:
The suffix -algia denotes 'pain' and is used following a combining form that specifies the type or location of pain, making the statement true.
Step-by-step explanation:
The suffix -algia, which means 'pain', is indeed typically used when preceded by a combining form that specifies the type of pain or the location of the pain. One common example is 'neuralgia', where 'neur-' refers to nerves, and '-algia' denotes pain. Therefore, when combined, 'neuralgia' refers to nerve pain. Similarly, 'myalgia' combines 'my(o)-' referring to muscle, and '-algia', indicating muscle pain. So the statement that the suffix '-algia' is used after a combining form is true.
