IPA: /ˌhaɪpəˈræɪsɪti/
KK: /haɪpərəˈsɪdəti/
A condition where there is an excessive amount of acid in the stomach or body.
The doctor diagnosed her with hyperacidity after she complained of frequent heartburn.
Hyperacidity is formed from "hyper-" (meaning excessive or above normal) and "acidity" (from Latin "acidus", meaning sour or sharp). The term describes a condition of having an excessive level of acidity, particularly in the stomach.
Think of 'hyper-' meaning excessive and 'acidity' referring to sourness — this helps you remember that hyperacidity means having too much acidity.
