The Japanese verb 'なめる (nameru)' has two distinct meanings. The first meaning is 'to lick', which refers to the physical action of passing the tongue over something. For example: the cat licked the milk「猫がミルクをなめた」(ねこがミルクをなめた). The second meaning is 'to underestimate', which is used when someone does not take a situation or person seriously. For example: don't underestimate me「私をなめるな」(わたしをなめるな). It's important to note that the context in which 'なめる' is used will determine which meaning is intended.
