Practice English articles, prepositions, or verb tenses through a mixed-topic ESL grammar generator that targets a learner's specific weak spot.
Three grammar habits quietly separate near-fluent English from fluent English, and none of them show up as a single memorizable rule. Articles trip up any learner whose first language has no equivalent system at all, Russian, Japanese, and Polish among them mark specificity through word order or context instead, so "I bought car" versus "I bought a car" versus "I bought the car" all sound like the same idea to someone reaching for English without that instinct built in. Prepositions resist rules even harder, in, on, and at follow a pattern for time and place only part of the way before the rest has to be memorized phrase by phrase, arrive in a country but arrive at an airport. Tense choice adds a third layer on top of both. This tool drills whichever one is actually causing trouble right now, instead of forcing every session through all three at once. Grammar focus is [GRAMMAR_FOCUS:select:Articles (a, an, the, zero article),Prepositions (in, on, at, and verb + preposition combinations),Verb tenses (mixed review across common tenses),Mixed practice across all three]. CEFR level is [CEFR_LEVEL:select:A1 (beginner),A2 (elementary),B1 (intermediate),B2 (upper intermediate),C1 (advanced)]. I need [DRILL_COUNT:number:10-40] items. If the learner's first language is known, name it in [L1_LANGUAGE?] so items target the specific gap that language tends to create, otherwise build general-purpose items covering the mistakes seen across learners regardless of background. For articles, build items where the difference between a, the, and no article at all actually changes the meaning of the sentence, not just its grammaticality. Introducing something for the first time needs a or an, referring back to something already established needs the, and a general or uncountable statement usually takes no article. For prepositions, pair each item with a fixed expression rather than a rule alone, since "depend on," "arrive at," and "married to" have to be learned as set combinations, and group a handful of commonly confused pairs together in the same set so the contrast does the teaching. For verb tenses in this mode, keep the drill lighter than a dedicated tense generator, mixed review items across the tenses a learner is most likely to encounter day to day rather than a deep dive into any single pair. Once a set is built, check real writing against the same rules directly, since a drill teaches the rule and reviewing an actual sentence catches where it didn't stick yet.

Get Early Access"I bought car," "I bought a car," "I bought the car," three sentences that sound like the same idea to a learner whose first language has no article system at all. Russian, Japanese, and Polish among others mark specificity through word order or context instead, so English articles get learned as an explicit set of rules rather than a feel for what sounds right. Prepositions cause a separate kind of trouble, in, on, and at follow a pattern for time and place only part of the way before the rest turns into phrase-by-phrase memorization.
Set [GRAMMAR_FOCUS] to articles, prepositions, verb tenses, or a mixed drill across all three, choose [CEFR_LEVEL] from A1 through C1, and name [L1_LANGUAGE] if known so items target that language's specific gap. Article items isolate the actual meaning shift between a, the, and no article rather than testing grammaticality alone. Preposition items pair each choice with a fixed expression, "depend on," "arrive at," since those combinations get memorized as units, not derived from a general rule.
For a deep pass on tense alone, especially present perfect versus simple past, the ESL verb tense practice generator goes further than the lighter mode here. Once a set is built, check real writing against the same rules with the articles checker or the prepositions of time and place explainer. Open a finished set in the Dock Editor to keep it next to whatever you're writing.
Paste this prompt into the Dock Editor, ChatGPT, Claude, or Gemini, then set [GRAMMAR_FOCUS] to articles, prepositions, verb tenses, or a mixed drill across all three.
Choose [CEFR_LEVEL] from A1 through C1 so item complexity matches the real level.
Fill in [L1_LANGUAGE] to target the specific gap that language tends to create, or leave it blank for general practice.
Check that each article or preposition item explains what actually changes when the choice changes, not only which answer is technically correct.
Target the one weak spot slowing a specific piece of writing down, articles one week, prepositions the next, instead of running the same generic grammar review every session.
