Uso de Adjetivos Cortos en Forma Comparativa

Understanding how to compare two people or things is one of the most practical skills in English. When you want to say that someone is older, taller, or bigger than another person, you need comparative adjectives — and the rules for short adjectives are straightforward once you learn the pattern.

What are comparative adjectives and when do you use them?

A comparative adjective is used to express the difference between two people or two things [0:14]. For example, in the sentence "My sister is older than my brother," you are comparing two people and their age. The word older is the comparative form of old.

The key structure is simple: subject + comparative adjective + than + the second element. This pattern stays consistent no matter which short adjective you choose.

How do you form the comparative of one-syllable adjectives?

The rule is clean and direct: when an adjective has only one syllable, you add -er at the end to create the comparative form [0:46].

• Bright → brighter.
• Dark → darker.
• Old → older.
• Young → younger.
• Small → smaller.
• Short → shorter.
• Tall → taller.

Notice how each of these words has just one syllable. You simply attach -er and the transformation is complete [1:24].

What happens when the adjective ends in a vowel and consonant?

There is an important spelling exception to keep in mind. If a one-syllable adjective ends in the combination of vowel + consonant, you must double the final consonant before adding -er [1:43].

Look at the word big: B (consonant) + I (vowel) + G (consonant). Since it ends in that vowel-consonant pattern, the G is doubled:

• Big → bigger (two Gs).
• Sad → sadder (two Ds) [2:12].
• Wet → wetter (two Ts) [2:44].
• Thin → thinner (two Ns) [2:44].

This doubling rule prevents confusion in pronunciation and keeps the vowel sound short.

How do you know when NOT to double the consonant?

Not every adjective ending in a consonant needs doubling. The word large is a great example [3:49]. It already contains the consonant cluster you need — L-A-R-G — and it ends in the silent e. In cases like this, you simply add -r instead of -er:

• Large → larger (spelled L-A-R-G-E-R, not L-A-R-G-G-E-R).

The trick is to check whether the last three letters follow the vowel-consonant pattern. If they do, double. If they don't, just add -er.

How can you practice these comparative forms?

Putting these rules into action with real sentences makes a big difference. Here are some examples from practice exercises [3:02]:

• "Her belly is bigger than her husband's." — Double G because big ends in vowel + consonant.
• "He is taller than her." — Double L, then add -er [3:20].
• "The green baskets are larger than the white one." — No doubling needed; just add -r [3:49].

When you practice, pay close attention to spelling. The meaning might be clear when speaking, but written accuracy matters in exams and professional communication.

To summarize the pattern in a quick reference:

• One syllable → add -er: old → older.
• Ends in vowel + consonant → double the consonant, then add -er: big → bigger.
• Ends in silent e → just add -r: large → larger.
