In this work, we have considered a non-canonical scalar field dark energy\nmodel in the framework of flat FRW background. It has also been assumed that\nthe dark matter sector interacts with the non-canonical dark energy sector\nthrough some interaction term. Using the solutions for this interacting\nnon-canonical scalar field dark energy model, we have investigated the validity\nof generalized second law (GSL) of thermodynamics in various scenarios using\nfirst law and area law of thermodynamics. For this purpose, we have assumed two\ntypes of horizons viz apparent horizon and event horizon for the universe and\nusing first law of thermodynamics, we have examined the validity of GSL on both\napparent and event horizons. Next, we have considered two types of\nentropy-corrections on apparent and event horizons. Using the modified area\nlaw, we have examined the validity of GSL of thermodynamics on apparent and\nevent horizons under some restrictions of model parameters.\n
