Comparatives and Superlatives
Very often when we compare different objects or events. As we tend to be as colorful as possible, using only comparative or superlative form of adjectives is not always enough.
Because of this, we begin to add adverbs or special constructions such as far, by far, much, a lot, a little etc.
The knowledge of the rules how to use the intensifiers of comparison usually indicates an advanced student.
Comparative and superlative
The comparative form of an adjective compares two things (taller, more polite); the superlative picks out the extreme of three or more (the tallest, the most polite). Short adjectives usually take -er and -est suffixes (tall → taller → tallest), while longer adjectives use more and most (expensive → more expensive → most expensive). A handful are irregular and you simply have to memorise them: good → better → best, bad → worse → worst.
Getting comparatives and superlatives right matters because comparing is something you do constantly — and the wrong form (more taller, the most best) sounds clearly off.
Adjective
An adjective is a word that describes a noun or pronoun — giving more information about its quality, state, or identity. Adjectives sit either before the noun (a tall building) or after a linking verb (The soup is hot), and they answer questions like what kind?, which one?, or how many?
Getting adjectives right matters for two everyday reasons: their position is fixed (you can't say a redly dress), and when you stack several before a noun, English follows a strict order — opinion, then size, then age, then colour. Break that order and the sentence sounds off even when each word is correct.
Adverb
An adverb modifies a verb, an adjective, or another adverb — adding information about how, when, where, how often, or to what degree something happens: she sings beautifully, unbelievably fast, we go there often. Many adverbs end in -ly, but plenty don't (well, fast, hard, almost).
Adverbs matter because they're how you add nuance without piling on extra clauses. Used well, a single adverb can sharpen a vague sentence (she answered → she answered honestly), but misplace one and the meaning drifts in a way native speakers immediately notice.
Modifier
A modifier is an optional element in a clause or phrase that adds information about another element — usually an adjective describing a noun (a red ball) or an adverb describing a verb, adjective, or another adverb (walked slowly, very tall). The defining feature: remove a modifier and the sentence still works grammatically.
Modifiers are how you add detail without changing the core meaning. Misplace one (Walking down the road, a vulture loomed) and you get a dangling modifier — one of the most common style problems in writing.
Morphology
Morphology is the study of how words are built — their internal structure, the parts they're made of (roots, stems, prefixes, suffixes), and how those parts combine to create related words. Happy → happiness → unhappy → unhappiness: same root, different morphology, different meanings.
For learners, morphology is what lets you guess the meaning of a new word from its pieces (pre- + judge = prejudge; -able added to read = readable). It also explains why English plurals, past tenses, and comparatives behave the way they do.
B2 | Upper Intermediate
B2 is the upper-intermediate level in the CEFR framework, sitting between B1 and C1. At B2 you can read editorials, follow most TED talks without subtitles, and hold extended conversations on abstract topics — including topics outside your everyday life.
Grammatically, B2 means flexible control of mixed conditionals, passive voice across tenses, reported speech with proper backshifting, and participle clauses. B2 is the standard target for university entrance exams (IELTS 5.5–6.5, TOEFL 87–109) and most skilled-migration thresholds — knowing whether you're there shapes your study plan.
Difficulty: Hard
The Hard difficulty tag marks questions and challenges aimed at upper-intermediate to advanced learners — typically B2 and above. Expect interacting rules, edge cases, distractors that look right at first glance, and contexts where the surface meaning and the grammatical answer don't match.
Filter by Hard when you're past the basics and want material that genuinely tests your understanding. These questions catch the gaps your textbook didn't — register-sensitive choices, exception cases, mixed conditionals, the difference between would have been and had been.
