I was sitting in a cramped exam hall last Tuesday, watching a student stare at a question about city life, and I could practically see the frustration boiling over. He knew the words, but he was stuck in that classic trap of trying to apply complex grammatical theories to a simple comparison. Most textbooks will spend three chapters explaining the theoretical nuances of how comparatives and superlatives work, but that’s not why you’re here. You aren’t here to pass a linguistics seminar; you’re here because you keep losing marks on things like “more better” or forgetting the “the” before a superlative.
I’m not going to waste your time with academic fluff or long-winded definitions that don’t help you in a high-pressure exam room. Instead, I am going to show you the practical shortcuts and the specific patterns that actually appear on the paper. I’ve kept a list of these errors for nineteen years, and I know exactly where the traps are laid. We are going to focus on turning these rules into automatic habits, so you can stop overthinking and start securing those easy marks.

Mastering the Adjective Comparison Rules
The first thing we need to address is the divide between short vs long adjectives. I see this error on exam papers every single week: a student writes “more tall” or “more big” because they are trying to apply a one-size-fits-all rule. It’s a simple distinction, but it’s an expensive one. If the word is one syllable, you add -er or -est. If it has three or more, you must use more or most. If you get this wrong, the examiner marks it as a fundamental lack of control, regardless of how brilliant your actual argument is.
Once you have the syllable count down, we have to tackle the outliers: the irregular adjective forms. Words like good, bad, and far don’t play by the standard grammar rules for adjectives. They change entirely—better, best, worse, worst. I tell my students to treat these like vocabulary items rather than grammar rules; you simply have to memorize them. If you try to force “gooder” into a sentence, you aren’t just making a slip; you are actively throwing marks into the bin.
The Short vs Long Adjectives Trap
This is where I see my “list of fifty” start to grow. Students often approach adjective comparison rules with a sort of “one size fits all” mentality, which is a recipe for disaster in a formal exam. I see it constantly: a student writing “more big” or “more fast” because they’ve memorized the idea of adding more, but they’ve forgotten the fundamental distinction between short vs long adjectives. If the word is a single syllable, you add that -er or -est suffix. Period. There is no middle ground, and the examiners certainly won’t give you the benefit of the doubt when you ignore this.
The real trouble starts when you hit those three-syllable words. Once you move into longer territory, you must stop trying to tack on endings and start using more and most in English instead. Writing “beautifuler” isn’t just a minor slip; it’s a visible error that signals to the examiner that you haven’t mastered the basic mechanics. It’s a simple distinction, but if you don’t internalize it, you’ll keep leaking marks on sentences that should have been effortless.
Five Ways to Stop Bleeding Marks on Comparisons
- Watch out for the “double comparison” trap. I see it in almost every exam paper: students writing “more better” or “more faster.” You only need one marker—either the suffix ‘-er’ or the word ‘more.’ Using both is a guaranteed way to lose marks for basic grammar.
- Don’t forget your ‘the’ with superlatives. It’s a tiny word, but it’s non-negotiable. You aren’t just saying something is “best”; you are saying it is “the best.” If you leave that ‘the’ out, the examiner knows immediately that your control of the language is shaky.
- Mind your spelling when adding suffixes. If an adjective ends in a consonant-vowel-consonant pattern, like ‘big,’ you must double that final letter: ‘bigger.’ It seems trivial, but these small slips add up to a very poor impression in a formal writing task.
- Remember that ‘less’ and ‘fewer’ are not interchangeable. This is one of those errors I’ve seen more than fifty times. Use ‘fewer’ for things you can count (fewer mistakes) and ‘less’ for things you can’t (less time). Mixing them up is a classic mistake that costs high-level candidates their top grade.
- Watch the ‘than’ spelling. I cannot tell you how many times I’ve seen ‘then’ used in a comparison. ‘Then’ refers to time; ‘than’ is for comparison. It’s a simple distinction, but in a high-stakes exam, it’s a mistake that looks incredibly careless.
Don't Let These Easy Marks Slip Away
At the end of the day, mastering comparatives and superlatives isn’t about memorizing a massive dictionary; it is about avoiding the repetitive slips that I see on exam papers every single week. We have looked at how to distinguish between short and long adjectives, and we have addressed the common pitfall of doubling up on modifiers. Remember: you either add “-er/-est” to the end of a short word, or you place “more/most” in front of a long one. You cannot do both. If you keep your focus on these specific mechanics, you will stop making those expensive, automatic errors that turn a high-scoring essay into a mediocre one. Precision is what separates the passing candidates from the top achievers.
I know that studying grammar can feel like a repetitive chore, much like practicing a difficult piece of music for a choir rehearsal. But just as we practice scales to make the melody seamless, you are practicing these rules to make your English feel instinctive. Don’t be discouraged if you trip up occasionally; the goal is to move these structures from your conscious thought into your permanent habits. Once you stop second-guessing whether to use “more” or “-er,” you will free up so much mental energy to focus on the actual content of your exam. You have the tools now—now, go out there and use them with confidence.
Frequently Asked Questions
What happens if an adjective is both short and long, like "clever" or "quiet"?
This is where I see my “error list” start to grow. Students get stuck because they think the rules are rigid, but English is a bit more fluid. For words like clever or quiet, you can actually use both: cleverer/more clever or quieter/more quiet. Both are grammatically correct. My advice? Pick one style and stick to it throughout your essay. Consistency is what keeps your marks high; don’t flip-flop mid-paragraph.
Can I use "more" and "-er" together if I'm trying to add emphasis, or is that an automatic mark deduction?
Oh, I see this one in my error log constantly. The short answer? Yes, it is an automatic mark deduction. I know you feel like “more faster” adds a certain punch, but in an exam, it just looks like you haven’t mastered the basic mechanics. It’s a double marking error. If the adjective takes “-er,” use it alone. If you want emphasis, use “much” or “far” instead. Save those marks for things that actually matter.
How do I handle irregular adjectives that don't follow the standard rules, like "far" or "bad"?
This is exactly why I keep my “error list.” Students often try to force these words into the standard rules, writing things like “badder” or “fartherer.” It’s a classic trap. You simply have to learn them as individual habits. “Bad” becomes “worse,” and “far” becomes “farther” or “further.” They don’t follow the rules because they are rebels. Memorize them now, or you’ll pay for it in your writing exam later.
