A whole thought needs someone and something they do — the same test your English room gave you, word for word, in a second language. Twenty-four cards, a quiz in three tiers and four workshop activities cover el sujeto and el verbo, the -ar verbs, and the one thing Spanish can do that English cannot: hide the doer inside the verb.
A whole thought needs someone, and something they do
Here is someone. El gato. You know exactly who is being talked about — and still nothing has happened. This is not a thought yet.
The two parts have names, and you already met them in English. The part that says WHO is the subject — in Spanish, el sujeto. The part that says WHAT THEY DO is the verb — el verbo. That is the same sentence you learned about English sentences, and it is true here word for word. What changes in Spanish is only this: the verb ending can carry the subject all by itself, so a whole thought can be one word long.
Two things people get wrong
⚠️People often think…
A long group of words is a whole thought and a short one is not.
El gato corre is three words and a whole thought. En la casa grande y roja is six words and is not one — it tells you where, and never says who or what happens. Length is not the test. The test is whether both parts are there.
Count the parts, not the words. This is the same test as in English.
⚠️People often think…
You always have to say yo, tú or él, the way English always says I, you or he.
In Spanish the END of the verb already says who. Hablo means I speak — the -o is the I. Hablas means you speak — the -as is the you. So yo hablo is correct but repeats itself, and Spanish speakers usually just say hablo. English cannot do this: ‘speak’ on its own tells you nothing.
The ending is the doer. Say yo only when you need to point.
Find the two parts
1Watch one
Is Ana canta en la escuela a whole thought?
Look for someone. Ana. That is the subject.
Look for something they do. Canta — she sings. That is the verb.
Both parts are there, so it is already a whole thought.
En la escuela tells you where. Useful, but it is not one of the two parts.
Yes. ✓ And take en la escuela away and Ana canta is still a whole thought — which proves the extra words were never doing that job.
2Do one with me
Take apart Los niños estudian español.
The part that says who is
The part that says what they do is
So is it a whole thought? Write yes or no.
💬One sentence, then you move on
Why is En la casa grande y roja not a whole thought, even though it is longer?
3Try one
Here is a whole thought of exactly one word: Canto. Write who is doing it.
I want a hint first
The doer is hiding on the end of the verb. Hablo, canto, camino — all of them end in -o, and all of them mean I.
💬Last one — then you’re done here
English needs two words to say I sing. Spanish needs one. What is the Spanish verb ending doing that the English one is not?
Where this goes
Where this lives
Every sentence you will ever write in Spanish, and the test you run on every one of them: is there someone, and is there something they do? It is the same test your English room gave you, and it did not change when the language did.
What this feeds
Next room: soy and estoy. Two Spanish verbs where English only has one — am — and the difference between them is exactly the difference between who you are and how you are today.
Write one whole thought in Spanish about someone in your house. Then underline the two parts.

Helpful Hints
🧭 The unit in one line
A whole thought = someone + something they do → el sujeto and el verbo → -ar verbs drop the -ar and take -o, -as, -a, -amos, -an → the ending already says who, so yo and tú are optional → no goes in front of the verb → length is never the test.
Count the parts, not the words. And read the end of the verb first.
🔑 The one idea
This is the sentence your English room already taught you, said again about Spanish: a whole thought needs someone and something they do. It did not change when the language did, because it was never a fact about English — it was a fact about thoughts. The one thing Spanish adds is that the verb ending carries the subject, so the doer can be inside the verb and a complete sentence can be a single word. English has no way to do that.
⚠️ Traps to avoid
Length is not the test. El gato corre is whole; En la casa grande y roja is not.
The verb ending already says who, so yo and tú are optional — hablo is complete on its own.
habla and hablas are one letter apart and mean different people. Read the end.
no goes in front of the verb: no hablo, never hablo no.
Ana y Luis counts as more than one, so the verb takes -n: cantan, not canta.
If YOU are in the group it is -amos; if you are not, it is -an.
¿Por qué? with two words asks why. Porque as one word answers it.

🎯 How you will be asked
“Is this a whole thought?” — and they are checking for both parts, not length.
“Underline the subject and circle the verb.”
“Fill the blank: Ana ____ en la escuela.” — with estudiar.
“Who is doing it in canto?” — the ending is the answer.
“Make this sentence negative.” — no goes in front of the verb.
✅ Before the test, can you…
Say the two parts a whole thought needs, without looking?
Give all five -ar endings and who each one means?
Find the subject and the verb in a sentence you have never seen?
Explain why Nado is a complete sentence and Tres gatos negros is not?
Make a sentence negative, and turn one into a question?
Join two whole thoughts with y, pero and porque?
📚 Go to the sources
These open another website and need the internet. Look up an -ar verb in the first two — a dictionary prints every ending in a table, which is the same five you just learned.
Look back at anything you missed — the hint that appeared is exactly what to reread tonight.
How sure did you feel?
Workshop
Sort twelve groups of words into whole thoughts and pieces, put a conversation back in order and watch the verb ending change with the doer, label the two parts of a sentence, then tell a friend why length is not the test.
