The phrase "an itching palm" is commonly used to describe someone who is greedy or has a strong desire for money. However, there are several other similar phrases that can be used in its place. For example, "money-hungry" or "avid for wealth" convey the same idea. "Acquisitive" and "covetous" are other synonyms, indicating a strong desire to acquire material possessions. Alternatively, "grabby" or "grasping" may be used to describe someone who is overly eager to obtain money or goods. Regardless of the synonym used, these phrases all convey a sense of greed or avarice, emphasizing a preoccupation with material wealth rather than other values.
