🇪🇸 The Challenge

Irregular plurals and pronunciation. Most plurals add -s, but many common words have irregular plurals (child/children, foot/feet) or unusual patterns.

🇲🇽🇨🇴🇦🇷 Irregular plural memorization

Problem: Spanish has regular plurals, English has many exceptions

Watch out: Applying -s to everything: 'childs', 'foots', 'tooths'

✅ Fix: Memorize the common irregular plurals as vocabulary

🧠 Mental Note: Top irregulars: child/children, man/men, woman/women, foot/feet, tooth/teeth, person/people

❌ 'two mans' → ✅ 'two men'

🇪🇸 Same irregular challenge

Problem: Spanish plurals follow predictable patterns

Watch out: Over-regularizing English plurals

✅ Fix: Some of the most common English words have irregular plurals!

❌ 'womans' → ✅ 'women'

🧠 Visual Explanation (The Mental Fix)

The Plural Patterns

Most plurals are easy, but watch for patterns! Regular: add -S book → books, car → cars -S, -X, -CH, -SH: add -ES bus → buses, box → boxes, church → churches -Y after consonant: -Y → -IES baby → babies, city → cities BUT: key → keys (vowel + y = just -s) -F/-FE: often → -VES wife → wives, knife → knives, leaf → leaves Completely irregular: man → men, woman → women child → children, foot → feet tooth → teeth, mouse → mice Same singular/plural: sheep, fish, deer, species

When in doubt, check if it ends in -s, -x, -ch, -sh (add -es), or -y after consonant (change to -ies).

🗣️ Pronunciation Guide

How Spanish speakers should pronounce this structure:

Plural -S has three sounds

Spanish Habit: Always pronouncing plural -s as /s/

English Reality: Three sounds: /s/, /z/, /ɪz/

Examples:

  • cats → /kæts/ (after voiceless sounds)
  • dogs → /dɒɡz/ (after voiced sounds)
  • buses → /ˈbʌsɪz/ (after s,z,sh,ch = extra syllable)

Practice: After voiced sounds (b,d,g,v,m,n,l,r + vowels), -s sounds like /z/

📖 How It Works

Irregular plural lists. Pronunciation practice for -s/-es endings.

🔑 Signal Words (Memory Anchors)

These words/phrases appear with this structure:

English Spanish Example

-ies (consonant+y) -ies babies, cities, countries

💬 Real Examples

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

Example 1: Common irregular: child/children

CORRECT: "The children are playing."

🇪🇸 Translation: "Los niños están jugando."

COMMON MISTAKE: "The childs are playing."

Why wrong? CHILD → CHILDREN (not 'childs'). Completely irregular.

🇲🇽 LatAm Trap: Must memorize: child/children, man/men, woman/women

Example 2: -Y to -IES

CORRECT: "I visited three cities."

🇪🇸 Translation: "Visité tres ciudades."

COMMON MISTAKE: "I visited three citys."

Why wrong? Consonant + Y → -IES: city → cities, baby → babies

BUT: key → keys, day → days (vowel + y = just add s)

Example 3: -F to -VES

CORRECT: "Autumn leaves are beautiful."

🇪🇸 Translation: "Las hojas de otoño son hermosas."

COMMON MISTAKE: "Autumn leafs are beautiful."

Why wrong? LEAF → LEAVES. Many -f/-fe words change to -ves

🇲🇽 LatAm Trap: Also: wife→wives, knife→knives, life→lives, wolf→wolves
Exceptions: roof→roofs, belief→beliefs
