“He prides himself — his wealth” বাক্যের শূন্যস্থানে সঠিক শব্দ হবে— ?

In the sentence “He prides himself his wealth,” the appropriate preposition to fill in the blank is "on," making the complete phrase “He prides himself on his wealth.”

The expression "to pride oneself on" is a well-established idiomatic phrase in English. It conveys a sense of personal satisfaction or self-respect regarding a particular quality or achievement. In this case, the individual's wealth is the subject of pride. This implies that he regards his financial status as an important aspect of his identity, and it is something that brings him pride.

Other options, such as "of," "for," and "in," do not convey the same meaning in this context. For instance, "pride oneself of" is not idiomatic in English; "pride oneself for" suggests pride about actions rather than attributes or possessions; and "pride oneself in" could work in some contexts but isn't the conventional preposition used for this specific phrase.

Thus, "on" is the most accurate and idiomatic choice, establishing a correct and meaningful relationship between the subject and what he takes pride in.
