The keyword "qq1221" functions grammatically as a noun. Specifically, it is an alphanumeric string that acts as a proper noun or a unique identifier. Its structure, a combination of non-standard letters and numbers, precludes it from being a conventional adjective, verb, or other part of speech.

The central point is that the string itself is the subject or object of discussion, not a descriptor of something else. ...
