Sentence Structure
Simple sentences
One subject + one verb can carry a full idea when the words are chosen well.
Why this happens
A simple sentence has one independent clause — one subject–verb core — but writers sometimes mistake short for simple or pack too many ideas into one clause with commas. Others add fragments thinking they are simple sentences. Recognising the single complete thought helps you control pace and combine ideas deliberately later.

Teaching note: Two subject–verb pairs need two clauses joined properly, not a comma splice.

CorrectShe runs every morning.
Teaching note: Running every morning has no finite verb — add a subject and main verb.

CorrectThe team celebrated loudly after the win was announced.
