Etymology

The term 'sensitized' is derived from the verb 'sensitize', which comes from the Latin word 'sensitivus', meaning 'sensitive'. This Latin term is rooted in 'sensus', which means 'sense' or 'feeling'. The prefix 'sen-' relates to perception and sensation. In the late 19th century, the term started gaining traction in the context of immunology and psychology, where individuals or organisms became more responsive to external stimuli or allergens after previous encounters. Over time, 'sensitized' has been adapted across various fields, including medicine, psychology, and even everyday conversations about heightened awareness or reaction to specific stimuli.
