You're missing a specific property where social constructs need to not exist without people agreeing they exist. It's not just about the multiple meanings - it's a social construct if it didn't exist before. "hammer" did exist. "hammer as a description of tools used to hurt people" doesn't until people agree it does. The interesting parts are that enough consensus emerged due to (some factors) to create that meaning, how did that consensus emerge, if it's isolated to some groups, etc.
