The suffix 'algia' means pain, and it is used in medical terms like 'neuralgia', which means pain of a nerve, and the adjective 'neuralgic', describing severe pain along a nerve.
Step-by-step explanation:
The suffix algia refers to pain. When used in medical terminology, it describes a type of pain or painful condition. Two common uses of this suffix are in the words neuralgia, which means pain of a nerve, and myalgia, meaning muscle pain. The part of the word neur refers to nerve, so when combined with algia, it specifies the type of pain. The word neuralgic is an adjective describing the type of pain that is usually along the path of a nerve, often sharp and severe.
