Hamlet says, "A little more than kin and less than kind". How does Hamlet play with words here, & what is he saying about his uncle?

In this line, Hamlet is using a play on words to express his disdain for his uncle, King Claudius. The phrase "a little more than kin" refers to the fact that Claudius is now both his uncle and stepfather, making their relationship closer in terms of family ties. However, "less than kind" suggests that despite this closeness, there is a lack of genuine kindness or affection between them. Hamlet is implying that although they are related, he does not feel any warmth or familial bond with Claudius, highlighting his suspicion and resentment towards him.
