बिल्ली (billii)

noun Mainly a straightforward noun for 'cat', with a well-known idiom about a cat crossing one's path and a couple of colloquial extended uses.
Sense 1 : cat (the animal)
noun, feminine
Synonyms: बिलाव (bilaav, male cat specifically)
Frequency: high
Cultural Note: In Delhi homes and streets, बिल्ली (billii) usually refers to street cats rather than pampered pets, so the word carries a slightly less domesticated, more 'neighborhood animal' feel than English 'cat' often does.
Common Mistakes: 1) Learners sometimes assume बिल्ली (billii) is used only for female cats since it ends in ई (ii), but it is the default word for 'cat' regardless of sex; बिलाव (bilaav) is used only when the male sex is specifically relevant.

Sense 2 : a cat crossing one's path (idiom of interruption/bad luck)
noun, feminine Occurs almost exclusively in the fixed phrase बिल्ली रास्ता काट गई (billii raastaa kaat gaii, 'a cat crossed the path') or बीच में बिल्ली आ गई (biich men billii aa gaii, 'a cat came in between'), used to explain a sudden hitch, quarrel, or bad omen interrupting something.
Frequency: medium
Cultural Note: There is an old superstition that a black cat crossing your path is inauspicious, and this idiom about दो लोगों के बीच बिल्ली आना (do logon ke biich billii aanaa, 'a cat coming between two people') is commonly used when two friends suddenly stop talking or a plan falls through for no clear reason.
Common Mistakes: 1) This idiom is about interruption or ill omen, not literally about cats; learners sometimes translate it too literally and miss the figurative 'something went wrong/came between us' meaning.
Sample Sentences:
उन दोनों के बीच अचानक बिल्ली आ गई। A cat suddenly came between the two of them (they suddenly stopped talking).
