vt. to fasten or join one thing to another
vt. to associate someone or something with a group or role
vt. (computing) to include a file with an email or message
The word "attach" entered English via Old French atachier, meaning "to fasten or fix." The Frankish root stakōn (related to "stake") reflects the idea of securing something firmly. Over time, the prefix at- (from Latin ad-) reinforced the directional sense of "connecting to." The modern meaning expanded metaphorically to include emotional or digital connections (e.g., attaching files).
