What does my mean?
My is a possessive determiner that identifies something as belonging to, associated with, or concerning the speaker or the person being addressed. It commonly introduces nouns and noun phrases: “my home,” “my colleague,” or “my concern.” The word is equally natural in formal writing and everyday conversation, although the tone of the surrounding sentence determines whether the possession is personal, emotional, emphatic, or simply descriptive. My is related to the pronoun I and historically derives from an Old English genitive form meaning “of me.” Unlike mine, my normally requires a following noun and therefore functions as a determiner rather than as an independent possessive pronoun. In literary or old-fashioned contexts, my can also serve as an exclamation, as in “My, what a mess!” Although very short, my is structurally important because it turns a noun or name into something explicitly associated with the speaker or listener.
A determiner indicating that the noun it precedes belongs to, is associated with, or is concerning the speaker or the person being addressed.
"We agreed to put my proposal on the agenda."
It normally precedes a noun, proper name, or established noun phrase and is not normally used with ordinary plural nouns.
An exclamation expressing surprise, sympathy, admiration, or concern.
"My, how kind of you!"
This use is literary or old-fashioned and is less neutral than an exclamation such as “wow.”
The tiny word “my” began as a medieval way of saying “of me,” turning a simple possession into a personal connection.

Where does my come from?
My descends from Old English mīn, the genitive form of the first-person singular pronoun ic, meaning “me” or “of me.” In modern English it developed into a possessive determiner placed before nouns, while the related independent form became mine. The word has close cognates in other Germanic languages, including German mein, Dutch mijn, and Icelandic mín.
