The word 'supersensitive' is a modern English compound formed by attaching the intensifying Latin prefix 'super-' to the existing adjective 'sensitive'. The core concept of feeling, 'sentire' in Latin, is the ultimate source, giving rise to the semantic field of perception and reaction. By adding 'super-', meaning "over" or "beyond," the term logically constructs a meaning that exceeds normal levels of sensitivity. This follows a common pattern in English where Latin prefixes are used to amplify the degree denoted by a base word of Latin origin, creating a precise term for an extreme condition.

Structure: super (above, beyond) + sensitive (responsive to stimuli) - super: Latin origin, from the preposition 'super' meaning "above, over, beyond." Functions as a prefix indicating excess, superiority, or a higher degree. - sensitive: Latin origin, from 'sensitivus' (capable of sensation), from 'sentire' (to feel). Functions as the core adjective describing responsiveness.
