Etymology

Origin of attachment

First recorded in 1325–75; Middle English attachement “detention, distraint, seizure,” from Anglo-French; see attach, -ment

Explanation

Attachment is a sticky word: an email attachment fastens a file to an email, while someone who has an attachment to email loves email. Attachment brings things together. Attachment is a word that's equal parts mechanical and emotional. Many gadgets — such as cameras and tractors — have attachments that allow them to get more done, like a tractor attachment for plowing snow. People have attachments to bands, political movements, sports teams, hobbies, and each other. It's important for babies to develop attachments to their parents — this means they're bonding with their parents. Attachment is a lot like duct tape — it fastens people and things together.
