Subject and Predicate in the Sentence
The subject of a sentence is the person, place, thing, or idea that is doing or being something. The predicate, on the other hand, contains the verb and provides information about the subject. Let's break down the sentence "No man can serve two masters" to identify the subject and predicate.

Subject: No man
In this sentence, the subject is "No man." The subject is who or what the sentence is about, in this case, referring to a man. The word "No" acts as a determiner specifying the quantity or quality of the man, and "man" is the noun identifying the subject.

Predicate: can serve two masters
The predicate in this sentence is "can serve two masters." It contains the verb "can serve," which describes the action or state of the subject. The phrase "two masters" provides more information about the action the man can or cannot do, indicating that he cannot serve two masters simultaneously.
In summary, the subject "No man" identifies who the sentence is about, while the predicate "can serve two masters" provides information about what the man can or cannot do. This sentence follows the structure of subject-verb-object, where the subject performs the action described by the verb in the predicate.
