Yes, a compound subject consists of usually two simple subjects connected by "and".
At least two, unless the compound itself is considered a single simple subject.
Adjectives are used to modify both simple and compound subjects.
Yes, it is possible to use a compound subject in a simple sentence. A compound subject consists of two or more subjects that are connected by a coordinating conjunction such as "and" or "or." For example, "Sara and Emma went to the park" is a simple sentence with a compound subject "Sara and Emma."
Okay, a compound subject is two subjects into one, and a simple predicate is the same ending to both subjects. For example: Alan and Robin were found walking down the street. In the foregoing, Alan and Robin are the two subjects, also known as compound subject, while simple predicate was "were found." However, I added another predicate which was basically an adjective phrase, "walking down the street." But "were found" is a simple predicate.
Compound subjects have at least two parts joined by or . . . nor, not only . . . but also, or and, as in snacks and fruit juice, and each part may be singular or plural. A plural subject has just one word as the simple subject, but that word is plural (like plates). Finally, a collective subject contains a simple subject representing a group (such as jury, which describes a group of twelve); the collective subject may be singular (jury) or plural (juries).
A sentence can have one or more subjects, depending on its structure. Typically, a simple sentence contains a single subject, while compound sentences can have multiple subjects connected by conjunctions. Additionally, in complex sentences, there may be subordinate clauses with their own subjects. Thus, the number of subjects in a sentence can vary widely.
Not always
A compound subject has two or more subjects. In the sentence "Jerry and Carl went to the movies", "Jerry" and "Carl" are the compound subjects. In the sentence "Bob, the ice-cream man, and Sue, his new wife, are going to Memphis on their honeymoon", "Bob" and "Sue" are the simple compound subjects, and "Bob, the ice-cream man" and "Sue, his new wife" are the complete compound subjects.
