What does addy mean?
"Addy" is an informal English noun that serves as a casual shortening of the word "address." It refers to the place where someone lives or can be reached — a home address, an email address, or a mailing destination — and appears most often in relaxed spoken exchanges, text messages, and online chat. Saying "send me your addy" is friendly and breezy where "please provide your address" would be stiff and businesslike. The word belongs firmly to colloquial register: it suits everyday conversation among friends but would look careless on a form or in professional correspondence. In American slang, "addy" has also developed a separate sense referring to the prescription stimulant Adderall, a meaning found mainly in youth and drug-culture contexts and usually clear from context. For learners, "addy" is a useful marker of natural, conversational fluency — small, informal clippings like this are exactly what distinguishes native-sounding speech from textbook phrasing.

Etymology of addy
"Addy" arose as a simple colloquial clipping of "address," formed by keeping the stressed first syllable and adding a casual -y ending, a common pattern in English informal word formation (compare "brekkie" from breakfast). Its parent word, "address," traces back through Old French "adresser" to the Vulgar Latin *addirectiare, built on Latin "ad-" (toward) plus "directus" (straight), which also gives English words such as "direct" and "direction." The clipped form emerged in twentieth-century British and Australian speech and spread through internet and texting culture. A distinct American slang sense for Adderall developed separately in the early twenty-first century.
How addy is actually used
