अध्याय (adhyaay)

noun A straightforward one-sense noun: a chapter or section of a book, often with a formal or scholarly flavor.
Sense 1 : chapter (of a book or text)
noun, masculine
Synonyms: भाग (bhaag, part/section, broader), खंड (khand, volume/section)
Frequency: medium
Cultural Note: This is the word you will see printed at the top of every chapter in a Hindi textbook or novel -- अध्याय १ (adhyaay 1, 'Chapter 1'), and it carries a slightly bookish, formal register compared to everyday conversation. It is also the standard term for a chapter of a scripture, as in the eighteen अध्याय (adhyaay) of the Bhagavad Gita, so the word has a natural devotional or classical resonance alongside its ordinary use in schoolbooks.
Common Mistakes: 1) Learners sometimes use this for a 'chapter' of life or a phase of events (as English does figuratively); in everyday Hindi that figurative sense is understood but is less commonly reached for than in English -- speakers are just as likely to say दौर (daur, 'phase/era') or पड़ाव (padaav, 'stage') for a life-chapter. 2) Don't confuse with पाठ (paath), which means 'lesson' -- a textbook is divided into अध्याय (adhyaay) which are further broken into पाठ (paath) in some curricula, though the two are often used interchangeably in casual speech.
