What you’ll learn

What Is a Sentence?Understand that a sentence expresses one complete, finished idea.A sentence is a group of words that shares one whole thought. Unlike a stray word or an unfinished phrase, it feels complete. This lesson introduces the idea that a sentence needs certain parts to feel finished.
The Naming PartIdentify the naming part (subject) — who or what a sentence is about.Every sentence tells about a who or a what, called the naming part. People, animals, places, and things can all be naming words. Recognizing the naming part is the first step to building a sentence.
The Doing PartIdentify the doing part (verb) — the action in a sentence.The doing part tells what is happening: run, jump, sing, sleep. A naming part alone does not feel finished; adding a doing word gives the sentence its action and life.
Put Them TogetherCombine a naming part and a doing part to form a complete sentence.A sentence needs both a naming part (who or what) and a doing part (what happens). Snapping the two together turns loose words into one complete idea, such as 'The bird flies.'
Not Finished YetTell the difference between a complete sentence and a fragment.A fragment is only a piece of a sentence — it is missing the naming part or the doing part, so the idea feels unfinished. Complete sentences contain both parts and express a whole thought.
Dress It UpAdd a capital letter and an end mark to finish a sentence correctly.A written sentence begins with a capital letter and ends with a punctuation mark (period, question mark, or exclamation mark). These signals show where the idea starts and stops, wrapping the thought up neatly.

Questions this course answers

What does a sentence do?

A sentence shares one complete thought that feels finished — not just a single stray word.

Which one is a naming part (a who or a what)?

"The rabbit" names an animal, so it can be the naming part. "Jumps" is a doing word.

Which word is a doing part (an action)?

"Swims" tells what is happening — that is the doing part. The others are naming or describing words.

Which one is a whole sentence?

"Fish swim." has a naming part (fish) and a doing part (swim), so it is a whole sentence.

Why is "The big red" only a piece, not a sentence?

It leaves us hanging — there is no doing part and no finished idea, so it is a fragment.

How should a finished sentence be dressed?

A finished sentence begins with a capital letter and ends with a mark such as a period, question mark, or exclamation mark.
