IPA: /ɪnˈtɒlərəns/
KK: /ɪnˈtɑlərəns/
A condition where a person cannot accept or endure something, often referring to a lack of acceptance for different beliefs, opinions, or behaviors. It can also refer to extreme sensitivity to certain substances, like food or medicine.
Her intolerance to gluten made it difficult for her to enjoy many types of bread.
Intolerance is formed from "in-" (meaning not) and "tolerare" (meaning to bear or endure). The word describes a state of not being able to bear or endure something, particularly differing opinions or behaviors.
Think of 'not' ('in-') being able to 'bear' ('tolerare') something — that's why intolerance means an inability to accept differences.
