A clear system for short, long, and irregular adjectives — with exactly the form your comparison needs.
Short adjectives usually take -er/-est, while long adjectives use more/most. Important adjectives such as good and bad have irregular forms.

A structured ten-slide lesson for A2 learners. Hear two comparative forms in context, learn the rules for short, long, and irregular adjectives, and practise them with quotes and results. The whole arc takes about ten minutes and requires no signup.
A comparative places two people, things, or situations beside each other. In *“This supplier is cheaper than the other one,”* you compare the prices of two suppliers. A superlative does a different job: it selects the item with the highest or lowest degree of a quality within a group. *“This is the cheapest supplier”* therefore does more than compare one supplier with a second; it places that supplier at one end of a complete scale. This distinction guides every form choice. First ask: am I comparing two sides? If so, use a comparative such as cheaper, more reliable, or better. Am I identifying the top item in a group? Then use a superlative such as cheapest, most reliable, or best. Both jobs occur constantly in practical communication. You compare two quotes, evaluate the results of different months, or identify the most important point in a plan. The grammar turns a neutral adjective into a precise tool. Cheap becomes a statement about a difference; cheapest becomes a statement about a position inside a group.
Short adjectives usually build their comparison forms with endings. Add -er for a comparison between two sides and -est for the superlative. This produces the set *“cheap, cheaper, cheapest.”* The adjective remains recognisable, while the ending immediately signals the job of the form. Some words change their spelling. Big doubles its final consonant: *“big, bigger, biggest.”* Happy changes y to i: *“happy, happier, happiest.”* Learn these spelling changes as complete three-form sets rather than as isolated corrections. Do not add more or most when the adjective already carries the relevant ending. *“More cheaper”* marks the same comparison twice and is therefore wrong in the standard sentence. In a quote comparison, you might say *“This option is cheaper,”* or, within a group, *“This is the cheapest option.”* When checking a new form, identify the base adjective first, then the comparison job, and finally any spelling change the ending requires. This keeps meaning and written form connected without making the rule feel like a list of unrelated exceptions.
Long adjectives normally avoid comparison endings and instead use a separate word before the unchanged adjective. Use more for two sides: *“more reliable,” “more expensive.”* Use most for the superlative: *“the most reliable,” “the most expensive.”* The lesson's opening sentence places the two systems side by side: *“This supplier is cheaper, but the other one is more reliable.”* Cheap is short and takes -er; reliable stays unchanged after more. Keeping those routes separate prevents forms such as *“reliabler”* and *“more reliableer.”* Included support can be part of the comparison too: *“The more expensive option includes support.”* That sentence does not automatically judge which quote is better overall; it describes one difference in one quality. The superlative turns the same quality into a group position: *“This is the most reliable option.”* Learn more/most + adjective as one connected building block. The adjective needs no additional comparison ending because the word before it already makes the comparative or superlative function visible.
Several very common adjectives follow neither the ending pattern nor the more/most pattern. Their forms need to be learned as a set. Good becomes better and best: *“This result is better than last month's”* and *“This was our best quarter so far.”* Bad becomes worse and worst. With far, you will meet the comparative forms further and farther. The important point is not to manufacture a regular form such as *“gooder”* or a double form such as *“more better.”* The irregular comparative already carries all the grammatical comparison information. Repeat the forms rhythmically as three-part sets: *“good, better, best”* and *“bad, worse, worst.”* Then place each member in a short sentence. A neutral result can be good, a comparison of two results needs better, and a selection from all results needs best. That sequence connects shape and meaning. In status reports, these compact irregular sets let you describe progress or decline without building a long alternative expression. The forms look different, but their comparative and superlative jobs remain the same as in regular adjective sets.
After a comparative, than commonly introduces the second side: *“The first quote is cheaper than the second.”* German-speaking learners face a classic trap here because German als resembles English as. A comparison with a comparative form needs than, however: *“bigger than,”* not *“bigger as.”* A superlative inside a clearly defined group often uses the: *“This is the most reliable supplier.”* Do not turn that tendency into a rule claiming that every superlative must have the. A possessive determiner can occupy that position instead. *“Our best quarter so far”* is therefore correct and needs no additional the. The same principle appears in a phrase such as *“my best result.”* Ask not only whether the adjective is a superlative, but also which word already determines the noun phrase. In an ordinary group comparison, the is typical; with our or my, the possessive comes directly before best. This small exception prevents the incorrect form *“the our best quarter”* while preserving the useful connection between superlatives and groups.
The two most common errors for German-speaking learners come from transfer and double marking. First, German als is transferred as the similar-looking English as. This produces *“This option is cheaper as the other one.”* English needs than to introduce the second side after a comparative: *“cheaper than the other one.”* Second, learners add a comparison word to an adjective that is already fully comparative. The result is *“more better”* or *“more cheaper.”* Choose one route in English: an ending, more/most, or an irregular set. A practical checking routine asks three questions. Are you comparing two sides or selecting from a group? Is the adjective short, long, or irregular? Do you need than after the form, or does a determiner such as the or our already stand before the superlative? Apply these questions to realistic work statements: *“This supplier is cheaper.” “The other one is more reliable.” “This was our best quarter so far.”* Each sentence contains one visible comparison marker and gives it one clear job. That consistency makes both writing and speaking easier to check.
A comparative places two sides against each other: *“This quote is cheaper than that one.”* A superlative selects the highest or lowest degree within a group: *“This is the cheapest quote.”* Ask “two sides or a whole group?” to choose the right form.
English uses than after a comparative, not as transferred from German als. Better is already the irregular comparative of good, so more would mark the comparison twice. The correct forms are *“bigger than”* and simply *“better.”*
A grouped comparison often uses the: *“the most reliable option.”* A possessive can occupy that position instead, giving *“our best quarter”* or *“my best result”* with no additional the. The complete noun phrase matters, not just the adjective form.
American English tolerates more + a short adjective, such as *“more clear,”* more readily than British English. Exams expect the -er form with one-syllable adjectives, so *“clearer”* is the safe standard form for your own use.
Use *object-pronouns* (A1) to name the second side of simple comparisons clearly. *countable-uncountable* (A2) supports the nouns used in many comparison sentences. Next, *too-enough* (A2) develops the idea of a quality being above or below a useful limit.
The set is an example of suppletion: originally unrelated roots fused into one form paradigm. The same old Germanic pattern appears in German gut, besser, best-. That is why the comparison forms do not look like good.
