रोचक (rochak)

adjective A single-sense adjective meaning 'interesting' -- one of the standard bookish/formal ways to say something engages your attention.
Sense 1 : interesting, engaging
adjective
Synonyms: दिलचस्प (dilchasp), मनोरंजक (manoranjak, leans toward 'entertaining')
Frequency: medium
Cultural Note: You will meet रोचक (rochak) constantly in written Hindi -- newspaper headlines, textbook blurbs, a teacher praising a story as रोचक कहानी (rochak kahaanii, 'interesting story') -- but in casual chat with friends, दिलचस्प (dilchasp) or even the English loanword 'interesting' itself tends to come out first. Think of रोचक (rochak) as the word's slightly more polished, classroom-and-column register.
Common Mistakes: 1) Learners often reach for रोचक (rochak) as the default translation of 'interesting,' but in everyday speech दिलचस्प (dilchasp) is the word most people actually reach for first; रोचक (rochak) sounds a shade more bookish or formal, at home in a book review, a lecture, or a news write-up. 2) Because it is invariant, learners sometimes try to inflect it like a regular -आ adjective (e.g. adding an ई ending for feminine agreement) -- it stays रोचक (rochak) regardless of the noun's gender or number.
