To remove, get rid of or erase, especially written or printed material, or data on a computer or other device.

Usage: Use "delete" to describe the act of permanently removing text, files, or data from a computer or digital device so that it can no longer be accessed. This verb specifically refers to erasing information rather than just moving it elsewhere or saving it as a draft.
The word delete comes from Latin and originally meant to blot out or erase by smudging. Its modern meaning of removing data appeared around 1977, while the sense of omitting features from products emerged in the 1960s.
