Where does unzipped come from?
“Unzipped” is an English formation made by adding the prefix “un-” to “zip” and the past-tense and participial suffix “-ed.” “Zip” is an expressive English word associated with rapid movement and a sharp sound, while “zipper” was developed from the same verbal root to name the device that fastens an opening. The prefixed form “unzip” and its inflection “unzipped” follow ordinary English patterns of reversing an action while retaining the root's sound.
How unzipped is actually used
The expression is neutral when describing clothing, bags, or digital files. It becomes informal and sometimes provocative when describing an unfastened trouser fly, while figurative uses such as opening a discussion are generally conversational.
