Etymology
the word retrofitting is a modern english construction that combines a latin directional prefix with a germanic verb root. the latin prefix retro-, meaning "backwards," was adopted into english to denote a relationship to the past or to older systems. it is attached to the verb fit, which originates from middle english and carries the sense of making something suitable or adapting it. the suffix -ing transforms the verb into a noun denoting the ongoing process. thus, the literal logic of "fitting backwards" elegantly captures the concept of updating or equipping an existing structure with new components it originally lacked.
Analysis
retro: from latin retro, meaning "backwards, behind, in the past." serves as a prefix indicating backward direction or relation to the past. fit: from middle english fitten, meaning "to be suitable or proper." serves as the core verb root meaning to make suitable or to equip. ting: a modern english suffix derived from old english -ung, forming verbal nouns (gerunds) indicating the action or process.
