Prepositional Verbs and Adjectives
In English, many verbs and adjectives must be paired with specific prepositions, and there is rarely a strict logical rule to follow. For instance, a chaotic situation culminates in (not at) an event, and a terrible meal is devoid of (not from) flavor. Using the wrong preposition in these fixed phrases can easily disrupt the flow of otherwise advanced, formal writing.
This challenge tests your command of high-level vocabulary across several highly dramatic contexts. You will choose the correct prepositions to help a disgruntled employee draft a formal resignation letter, assist a seasoned detective with a poetic case report, and complete a starship captain's classified sci-fi log.
You will encounter 9 questions featuring a varied mix of single-choice, multi-choice, drop-down, and drag-and-drop formats. To succeed, you must recognize and correctly apply advanced pairings such as tantamount to, fraught with, impervious to, and conducive to.

The correct answers are to, of, in, and to.
Impervious to is a prepositional adjective meaning unable to be affected by something.
Devoid of means entirely lacking or free from something.
Culminate in is a prepositional verb meaning to reach a climax or point of highest development. (Note: "culminate with" is sometimes used in informal speech, but "culminate in" is the standard C1 level form).
Resigned to means accepting that something undesirable cannot be avoided.
Help the investigative journalist complete her scathing review of the Galactic Gateway project by dragging the correct prepositions into the text.
The billionaire's luxury space hotel project was fraught with technical issues from day one and utterly devoid of basic safety features. Experts warned that ignoring these structural flaws would inevitably culminate in a catastrophic disaster, but the CEO simply forced the engineers to resort to duct tape to fix the leaking hull.
The correct answers are with, of, in, and to.
fraught with: An adjective phrase meaning filled with something undesirable (e.g., fraught with danger).
devoid of: An adjective phrase meaning entirely lacking or free from something.
culminate in: A prepositional verb meaning to reach a climax or result in a specific final outcome. Beware of the common trap "culminate into"!
resort to: A prepositional verb meaning to turn to a disagreeable strategy to resolve a difficult situation.
Complete the harsh theater critic's review of last night's disastrous play by selecting the right pair of prepositions.
The actors seemed to revel ___ the absolute chaos of the second act, which ultimately culminated ___ the lead soprano accidentally setting her own wig on fire.
The correct answer is in / in.
The verb revel (meaning to get great pleasure from a situation) takes the preposition in.
The verb culminate (meaning to reach a climax or point of highest development) also requires the preposition in. It is a common mistake to say something "culminates into" a result, but "in" is the standard grammatical choice!
The correct answers are ignorant of, oblivious to, and unconcerned about.
Many advanced adjectives require specific dependent prepositions to connect them to their objects.
- Ignorant takes of (ignorant of the facts).
- Oblivious takes to (oblivious to the danger).
- Unconcerned takes about (unconcerned about the risks).
The distractors use the wrong prepositions: the correct forms are unaware of and heedless of.
The correct answers are to, with, of, and on.
Conducive to means making a certain situation or outcome likely or possible.
Fraught with is a prepositional adjective meaning filled with or destined to result in (usually something undesirable like danger or problems).
Apprise of is a formal verb phrase meaning to inform or tell someone about something. (It is a common trap to say "apprise about", but "of" is grammatically correct!)
Hinge on (or hinge upon) means to depend entirely on something.
The correct answers are scoffed at, rebelled against, and dispensed with.
Prepositional verbs consist of a verb and a specific preposition that must precede its object. Scoff at, rebel against, and dispense with are all perfectly valid prepositional verbs that fit this context.
The distractors are tricky because they sound similar, but flout and disregard are transitive verbs. They take direct objects without any prepositions (e.g., flouted the rules, disregarded the rules). Adding a preposition to them makes the sentence grammatically incorrect!
Help the seasoned detective finish her rather poetic case report by choosing the grammatically correct words.
The suspect's initial alibi was fraught ___ glaring inconsistencies, all of which seemed to stem ___ a misguided attempt to protect his hopelessly clumsy brother.
The correct answer is with / from.
The adjective fraught (meaning filled with or destined to result in something undesirable) is followed by with. Do not confuse it with "full of"!
The verb stem (meaning to originate in or be caused by) pairs with the preposition from.
The correct answers are devoid of, bereft of, and lacking in.
Adjectives describing a "lack" or "absence" of something often take very specific prepositions.
- Devoid and bereft both strictly take the preposition of.
- Lacking usually takes in when used as an adjective (though "lacking flavor" without a preposition is also correct when used as a participle).
The distractors pair the adjectives with the wrong prepositions: the correct collocations are deficient in and empty of.
Help the disgruntled employee draft their formal resignation letter by choosing the correct prepositions.
Your insistence on micromanaging every trivial detail is tantamount ___ a complete lack of trust, and my current salary is hardly commensurate ___ the immense stress I endure daily.
The correct answer is to / with.
The adjective tantamount (meaning equivalent in seriousness to) is always followed by the preposition to.
The adjective commensurate (meaning corresponding in size or degree) pairs with the preposition with.
Adjective
Adjective vs adverb: both describe things, but adjectives attach to nouns while adverbs attach to verbs. A quick answer (adjective → noun) vs answered quickly (adverb → verb).
An adjective modifies a noun or pronoun — telling you what kind, which one, or how many: a red car, something useful, three heavy boxes.
Diagnostic test: if the word describes a thing or person, use the adjective form. If it describes an action, you need the adverb (-ly) form instead.
Object
Object vs subject: the subject does the action; the object receives it. The cat (subject) chased the mouse (object). In English, word order (SVO) determines which is which — subject before verb, object after.
An object is the entity a verb acts upon: direct (I read the book), indirect (I gave her a book), or prepositional (I waited for him).
Diagnostic: ask "[verb] what/whom?" after the verb. The answer is the direct object. Ask "to/for whom?" for the indirect object. After a preposition? Prepositional object.
Phrase
Phrase vs clause: a phrase has NO subject-verb pair (on the table, the old man). A clause HAS a subject-verb pair (the man sat, because she left). This is the fundamental structural division in grammar — clauses contain phrases, not the other way around.
A phrase = group of words functioning as one unit: noun phrase, verb phrase, prepositional phrase, adjective/adverb phrase. No subject + verb.
Diagnostic: does the word group have both a subject AND a verb? Yes → clause. No → phrase. Name the head word to identify the phrase type (noun = NP, preposition = PP, etc.).
Preposition
Preposition vs particle: same words (in, on, up, off), different jobs. A preposition links to a noun (look at the book). A particle changes verb meaning without a noun (give up = quit). Test: is there a noun/pronoun after it forming a prepositional phrase? → preposition. Does it change the verb's meaning? → particle in a phrasal verb.
A preposition = small word connecting a noun to the sentence (time, place, manner, relationship). Choice is idiomatic per verb/adjective combination.
Diagnostic: struggling with which preposition to use? It's almost never about logic — look up the specific verb/adjective + preposition combination.
Verb
Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.
A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.
Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.
Collocations
Collocation vs idiom: both are fixed expressions, but collocations are transparent (you can guess the meaning from the words: heavy rain = a lot of rain), while idioms are opaque (kick the bucket ≠ literally kick anything). Collocations are about which words pair naturally; idioms are about hidden meaning.
Collocations are habitual word combinations: make a decision, strong coffee, take a shower. Grammar allows alternatives, but fluency demands the conventional pairing.
Diagnostic: if the meaning is clear but the combination sounds "off" to native ears (do a mistake instead of make a mistake) — it's a collocation issue.
C1 | Advanced
C1 vs C2: C1 means fluent and flexible use with occasional gaps in very unfamiliar domains. C2 means native-like command of idiom, irony, and register across any subject. If you can handle advanced grammar but still miss cultural nuance or very rare idioms, you're C1.
C1 is the advanced CEFR level: inversion, cleft sentences, subjunctive mood, advanced conditionals, and precise register control in professional and academic contexts.
Diagnostic: can you write persuasively in different registers and catch subtle irony? Consistently → C2. Sometimes → C1.
Hard
Hard vs Medium: Medium tests one rule with realistic distractors. Hard tests interacting rules, edge cases, or context-dependent answers where multiple options seem correct until you think deeply. If you're scoring 80%+ on Medium, try Hard to find your real gaps.
The Hard tag filters for B2+ challenges with layered difficulty: rule interactions, subtle distractors, and contexts that demand genuine grammatical reasoning.
Diagnostic: if Hard questions feel impossible, drop to Medium and master the individual rules first. Hard assumes you already know each rule — it tests whether you can apply them together.
