लेना-देना (lenaa-denaa)

noun A fixed compound noun built from लेना (lenaa, 'to take') and देना (denaa, 'to give'), meaning 'connection/concern/dealing with something.' Used almost exclusively in negative or interrogative sentences about relevance or involvement.
Sense 1 : connection, concern, involvement (usually denied)
noun, masculine Almost always appears with से (se) marking the thing one has (or lacks) concern with, e.g. 'X से कोई लेना-देना नहीं' (X se koii lenaa-denaa nahiin, 'to have nothing to do with X'), and with the verb होना (honaa).
Synonyms: मतलब (matlab), वास्ता (vaastaa), संबंध (sambandh, formal), ताल्लुक़ (taalluq)
Frequency: high
Cultural Note: You will hear this constantly in Delhi arguments and gossip: 'मुझे इससे कोई लेना-देना नहीं है' (mujhe isse koii lenaa-denaa nahiin hai, 'I have nothing to do with this') is the classic way to distance yourself from a mess or a fight that isn't yours. It literally means 'taking-giving,' capturing the idea that any real relationship involves an exchange -- so having 'no लेना-देना' means the relationship itself doesn't exist.
Common Mistakes: 1) Learners try to use this word to mean literal 'giving and taking' (like exchanging objects) -- in everyday speech it has shifted almost entirely to the abstract sense of 'concern/relevance,' not physical exchange. 2) The negative form कोई लेना-देना नहीं (koii lenaa-denaa nahiin) is far more common than any positive use, so learners should first learn it as a fixed phrase for denying involvement rather than as a free-standing noun. 3) The postposition is से (se), not को (ko) or का (kaa), which learners sometimes default to by analogy with संबंध (sambandh)।
