Abstract: 

We will present the results from our recent studies(*) of 31 local LINERs (z < 0.025) mainly drawn from the Palomar Survey, on the basis of optical long-slit spectroscopic observations with TWIN/CAHA, ALFOSC/NOT and HST/STIS. We explored the AGN-nature of both type-1 and type-2 LINERs by studying  the broad Hα component (originated in the broad line region). Then, we derived a reliable interpretation of the different component of  emission lines by studying their kinematics and ionization mechanism.
