Medium A1A2

The 'Do/Did' support. Romance languages (Spanish/Italian) usually conjugate the main verb directly for questions. English requires an auxiliary (Do you go? vs ¿Vas?).

🎯 Why This Matters

Foundation for constructing 90% of English sentences.

Learning Outcome

Ability to ask questions and build negations.

🇪🇸 The Challenge

The 'Do/Did' support. Romance languages (Spanish/Italian) usually conjugate the main verb directly for questions. English requires an auxiliary (Do you go? vs ¿Vas?).

🇲🇽🇨🇴🇦🇷 Missing the auxiliary

Problem: Spanish forms questions with intonation alone

Watch out: Saying 'You speak English?' instead of 'Do you speak English?'

✅ Fix: For questions without be/have/modal, always start with DO/DOES/DID

🧠 Mental Note: Every question needs either: IS/ARE/WAS/WERE, HAVE/HAS/HAD, CAN/WILL/etc., or DO/DOES/DID

❌ 'You understand?' → ✅ 'Do you understand?'

🇪🇸 Double marking the past

Problem: Wanting to show past tense on both auxiliary AND main verb

Watch out: Saying 'Did you went?' instead of 'Did you go?'

✅ Fix: DID already carries past tense. Main verb stays in base form.

❌ 'Did she saw the movie?' → ✅ 'Did she see the movie?'

🧠 Visual Explanation (The Mental Fix)

The Helper Robot

Think of DO/DOES/DID as a helper robot 🤖 that you MUST call for questions and negatives: Spanish way (no robot): ¿Hablas español? (just invert or add ?) English way (robot required): DO you speak English? 🤖+you+speak The Robot's Rules: 1. Robot takes the tense (DO→DID in past) 2. Main verb stays in base form 3. Robot goes BEFORE the subject in questions

No robot, no question! If there's no be/have/modal, you MUST use do/does/did.

🗣️ Pronunciation Guide

How Spanish speakers should pronounce this structure:

Contractions are natural

Spanish Habit: Pronouncing 'do not' as two separate words

English Reality: Native speakers almost always use contractions: don't, doesn't, didn't

Examples:

  • don't → /doʊnt/ (one syllable)
  • doesn't → /ˈdʌznt/ (sounds like 'duznt')
  • didn't → /ˈdɪdnt/ (sounds like 'didnt')

Practice: Using full forms 'do not' sounds overly formal or emphatic

🔑 Signal Words (Memory Anchors)

These words/phrases appear with this structure:

English Spanish Example
do/does (auxiliary for present) Do you work here? / Does she speak Spanish?
did (auxiliary for past) Did you see that? / ¿Viste eso?
don't/doesn't no (+ verbo) I don't know / No sé
didn't no (+ verbo pasado) She didn't come / Ella no vino

💬 Real Examples

Let's see this structure in action with correct vs incorrect usage:

Example 1: Question formation

CORRECT: "Do you like pizza?"

🇪🇸 Translation: "¿Te gusta la pizza?"

COMMON MISTAKE: "You like pizza? / Like you pizza?"

Why wrong? English requires DO for questions with regular verbs

🇲🇽 LatAm Trap: In Spanish, you just change intonation: '¿Te gusta?' English needs the auxiliary!

Example 2: Negative formation

CORRECT: "I don't understand."

🇪🇸 Translation: "No entiendo."

COMMON MISTAKE: "I no understand. / I understand not."

Why wrong? English uses DO + NOT (don't), not just 'no' before the verb

🇲🇽 LatAm Trap: Spanish puts 'no' directly before verb. English needs DON'T!

Example 3: Past tense with DID

CORRECT: "Did you go to the party?"

🇪🇸 Translation: "¿Fuiste a la fiesta?"

COMMON MISTAKE: "Did you went to the party?"

Why wrong? DID already carries the past tense. The main verb must stay in base form (go, not went)

DID + base form, never DID + past form
