Final answer:
The subject-verb-object (SVO) sentence pattern is the simplest and most common sentence structure in English grammar.
Step-by-step explanation:
In English grammar, the subject-verb-object (SVO) sentence pattern is indeed considered the simplest and most common sentence structure. In this pattern, the subject performs the action (verb) on the object.
For example: John (subject) ate (verb) an apple (object).
However, it is important to note that there are other sentence patterns, such as subject-verb (SV) or subject-object (SO), which can also be simple depending on the context.
