What is Machiavelli's definition of liberal? Why is it not good for a prince to be a liberal?

He says that it should be hidden if done at all,

"liberality exercised in a way that does not bring you the reputation for it, injures you; for if one exercises it honestly and as it should be exercised, it may not become known."

It can paint the Prince as weak. Also ,liberal policy means spending more money which means raising taxes. People don't like high taxes, even today!

A prince should not liberal. When he will be liberal, some how it will hamper his position.
