The keyword "olx" functions primarily as a proper noun. As a proper noun, it specifically names a particular entity: the global online marketplace company. This classification is its core grammatical identity, similar to other corporate names like "Google" or "Amazon."
In syntactic analysis, its role as a proper noun allows it to function as the subject of a sentence (e.g., "OLX operates in over 40 countries."), a direct object (e.g., "The user checked OLX."), or the object of a preposition (e.g., "He posted an ad on OLX."). While it can be used attributively to modify another noun (e.g., "the OLX platform," "an OLX listing"), in this context it acts as a noun adjunct or a proper adjective, deriving its meaning from the core proper noun. A secondary, informal usage may see it "verbed" (anthimeria), as in "to OLX an item," meaning to list it for sale on the platform, but this is a colloquial adaptation and not its formal grammatical part of speech.
For the purpose of structuring an article, establishing "olx" as a proper noun is the critical first step. This positions the company or platform itself as the central subject of discussion. Any analysis of its business model, market impact, or user experience stems from this foundational understanding of it as a specific, named entity. Therefore, the main point of the article would be the entity identified by this proper noun.
