Computer goes back over 400 years. Computer referring to the ‘electronic device (or system of devices) which is used to store, manipulate, and communicate information’ isn’t found until the 1940s, but computer as a machine for performing calculations dates to 1869, according to current OED research.

The term for messages sent via the Internet (or a system for sending these messages) comes from the late 1970s; it is the obsolete email meaning ‘enamel’ that is found as far back as 1594, from the (still current) French word émail, ‘enamel’.

The word punk first entered the mainstream thanks to the punk rock music scene in the 1970s. Punk had already had a long and varied history, though. It is first found in the 16th century, designating a prostitute. After this, it had various different sexual connotations. Later still it was used of a coward, and an amateur, before being reclaimed and celebrated by rebellious 1970s music fans.

The earliest sense of crib is a ‘barred receptacle for fodder used in cowsheds’. More surprisingly, the informal use of crib, chiefly North American, to mean ‘a person’s apartment or house’ has a long heritage. Shakespeare himself used crib to mean ‘a small habitation’ or a confined space, in Henry IV, Part 2: ‘Why rather, sleep, liest thou in smoky cribs, Upon uneasy pallets stretching thee and hushed with buzzing night-flies to thy slumber, than in the perfumed chambers of the great, under the canopies of costly state, And lulled with sounds of sweetest melody?’.

Earlier than The Hobbit (1937), hobbit (or hobbet) – albeit with an entirely different etymology – was used to mean ‘a seed-basket’ or a local measure meaning two of something; these uses date as far back as 1863, according to OED research.
