English grammar filter: can a common noun act as a proper noun if the thing being referred to exists within a shared context? Please help to settle a dispute between my girlfriend and I.
In the area where we live, there is a farmer's market that opens on the weekend - the typical market of its sort, it sells fresh fruit, vegetables, and the like. The dispute is in how we should refer to it. My girlfriend says, "Let's go to Farmer's Market." I claim that this is incorrect - "farmer's market" is not a proper noun, and requires an article ("a", "the", "that") in order to be used in a sentence. It's a good natured argument, but we've wound ourselves in circles.
On the market's website
, you can see it in context: "Union Square Main Streets with The City of Somerville and The Federation of Massachusetts Farmers’ Markets brings the
Union Square Farmers Market each Saturday throughout the summer and early autumn. " (Emphasis mine.) Her position is that "farmer's market" is to be treated as a proper noun, because we share an understanding of which market she is referring to. Thus, you could say, "Let's go to Farmer's Market". She likens it to saying, "Let's go to Walmart." All attempts to convince each other have failed, and at so we turn to you for help!
Who is correct?
