The phrase "11 sep ko chutti hai kya" does not function as a single part of speech (e.g., noun, verb). Grammatically, it is a complete interrogative sentence or an interrogative clause. Its primary function is to pose a direct, closed-ended (yes/no) question. Understanding the phrase as a full sentence, rather than a single lexical category, is fundamental to analyzing its purpose and meaning in communication and information retrieval contexts.
A detailed grammatical analysis involves deconstructing the sentence into its constituent parts. "11 sep" is a noun phrase serving as a temporal adjunct, composed of a cardinal number ("11") and a proper noun ("sep"). The word "ko" is a postposition that marks the dative case, functioning here similarly to the English preposition "on" to specify a point in time. "Chutti" is a common noun meaning "holiday" or "leave." The term "hai" is an auxiliary verb, specifically the present indicative form of "to be" (is/are). Finally, "kya" is an interrogative particle which, when placed at the end of a declarative statement in Hindi, converts it into a question.
In practical application, such as in natural language processing (NLP) or search engine algorithms, the entire string is interpreted as a single functional unit: an informational query. While a syntactic breakdown reveals the individual parts of speech, the semantic value and user intent are derived from the phrase as a whole. The phrase's classification as an interrogative sentence is its most salient feature, signaling a direct request for factual information about the status of a specific date.
