Prepositions and Articles for Turkish Speakers: the, a, in, on, at
Turkish has no articles and uses suffixes instead of prepositions — so when you switch to English, you face a double gap. You might say I went to store (missing the), She is teacher (missing a), or I arrived in the airport (should be at). These aren't random mistakes — they come directly from how Turkish works.
This challenge targets both gaps at once. You will practice adding the and a/an where Turkish uses nothing, choosing between in, on, and at for places and times (Turkish uses a single locative suffix -de/-da for all three), and nailing adjective+preposition collocations like good at, interested in, and afraid of — fixed pairings that have no equivalent pattern in Turkish.
You'll work through 12 questions in a mix of single-choice, multi-choice, drop-down, and drag-and-drop formats featuring missing cats, spy missions, time travelers, and alien blog posts — all set in Turkish cities.

Correct Answers
The correct answers are in, on, on, and the.
in Istanbul: We use "in" for cities and countries. (Be careful not to say "arrived to"!)
on a sunny Tuesday: We always use "on" for days of the week, even if there is an adjective like sunny in front of it.
on a ferry: For large public transport where you can walk around (like a bus, train, or ferry), we use "on".
the captain: We use "the" because there is only one specific captain of that ferry. (Turkish does not have a direct equivalent for "the", so remember to include it when talking about specific nouns!)

Help Buster the dog complain to the neighborhood cat about his owners.
My humans are ___ work all day, leaving me to guard the couch!
The correct answer is at.
To describe someone's location at their job, English uses the set phrase at work with no article. Saying "at the work" or "in work" is grammatically incorrect in this context.
The correct answers are at, at, the, and an.
at home / at midnight: In English, we use "at" for specific locations like home or work, and for specific clock times like midnight. (Turkish speakers often use the locative suffix -de/-da for all of these, which can make choosing between in, on, and at tricky!)
the roof: We use "the" because we are talking about a specific roof (the roof of the museum).
an unusually: We use "an" instead of "a" because the next word (unusually) starts with a vowel sound.
Article
Articles are a small group of determinatives that signal whether a noun refers to something specific (the book) or something general (a book). English has three: the definite article the, the indefinite articles a/an, and the zero article — the meaningful absence of any article (Coffee keeps me awake).
Articles are one of the trickiest parts of English for non-native speakers because the choice depends on context, not just the noun itself. Get them right and your writing instantly sounds more natural; miss them and even simple sentences feel "off" to a native ear.
Countable and uncountable
In English, nouns split into two groups based on whether you can count them. Countable nouns (chair, book, idea) take a/an, form plurals (chairs), and pair with many, few, several. Uncountable nouns (water, furniture, advice, information) take no article in their general sense, have no plural, and pair with much, little, some.
This distinction matters because it controls article choice, plural marking, verb agreement, and quantifier selection — fewer chairs vs less water, an advice (wrong) vs some advice. It's one of the most common error sources for learners from languages without this split.
Determiner
A determiner is a word that comes before a noun to clarify what it refers to: which one, how many, whose. The English determiners include articles (a, the), demonstratives (this, that), possessives (my, your), quantifiers (some, many, few), and distributives (each, every).
Most singular countable nouns in English require a determiner — I bought book is wrong; you need I bought a book or I bought the book. Determiner choice signals how much information you assume the listener already has, so getting it right shapes how natural your speech and writing sound.
Noun
A noun is a word that names something — a person, place, thing, idea, action, or quality. Nouns are one of the open word classes in English, alongside verbs, adjectives, and adverbs. They typically appear as the subject or object of a clause, after articles or adjectives, and as the head of a noun phrase.
Recognising nouns reliably is the foundation for nearly every other grammar topic — agreement, articles, plurals, possessives, and prepositions all depend on it. Get this right and the rest of English grammar starts to fall into place.
Phrase
In grammar, a phrase is a group of words (sometimes a single word) that functions as a single unit in a sentence — but doesn't include a subject + verb pair the way a clause does. Common types: noun phrase (the old red car), verb phrase (has been running), prepositional phrase (on the table), adjective phrase (incredibly tired), adverb phrase (very quickly).
Phrases are the building blocks between individual words and full clauses. Recognising them helps you see how sentences hold together — and where you can break, expand, or rearrange them without losing meaning.
Preposition
A preposition is a small word that links a noun or noun phrase to other parts of the sentence — usually marking time, place, or relationship: in, on, at, to, from, with, over, under, between, during. The book on the table, We met at noon, She lives in Berlin.
Prepositions are deceptively small. Their meaning shifts dramatically by collocation (depend on, good at, afraid of), and their choice rarely translates directly between languages. Picking the right preposition is one of the trickiest, most idiomatic-sounding parts of English.
Collocations
Collocations are combinations of words that habitually occur together in a fixed order — make a decision (not do a decision), strong coffee (not powerful coffee), heavy rain (not thick rain). The grammar would allow either pairing, but native speakers consistently pick one and reject the other. Common patterns include verb + noun, adjective + noun, adverb + adjective, and adverb + verb.
Learning vocabulary as collocations rather than isolated words is the single fastest way to sound natural in English. It's the difference between I made a big mistake and I did a big mistake — small, but immediately noticeable.
B1 | Intermediate
B1 is the intermediate level in the CEFR framework — the point where you stop relying on memorised phrases and start handling everyday English independently. At B1 you can describe experiences, explain opinions, and follow most clear standard speech on familiar topics like work, travel, and hobbies.
Grammatically, B1 means combining tenses with precision, building complex sentences, and starting to use passive voice, modal verbs for necessity and possibility, and verb patterns (gerund vs. infinitive). Knowing your level shapes what you study next: pushing too far ahead frustrates you; staying below your level wastes time.
Difficulty: Medium
The Medium difficulty tag marks questions and challenges in the middle of the difficulty range — typically suitable for A2 to B1 learners. Expect a single rule with realistic distractors, longer sentences, and contexts where you have to think before answering rather than reading off the obvious choice.
Filter by Medium when you're past the absolute basics and ready to consolidate. It's the level where most lasting progress happens — easy enough that you can finish without exhausting concentration, hard enough that getting it right means you've actually understood.
