The complete grammar foundation in one chapter — eight core rule sets that underpin Error Detection, Sentence Improvement, and every other topic in this series.
This final chapter consolidates the eight core grammar building blocks that everything else in this series depends on. Rather than eight separate chapters, they're grouped here since bank exams test them as a connected foundation rather than in isolation.
Nouns name people, places, things, or ideas. The key exam-relevant distinction is countable vs uncountable: countable nouns (book, chair) take "a/an" and plural forms; uncountable nouns (information, furniture, advice) never take "a/an" and have no plural form.
Pronouns replace nouns and must agree with their antecedent in number and gender. A frequent bank-exam trap is using "their" for a singular, gender-neutral antecedent like "each employee" — formally, "his or her" (or a rewritten plural subject) is preferred in strict grammar testing.
Verbs express action or state of being and must agree with their subject in number. Watch for linking verbs (is, seem, become) that connect the subject to a description rather than showing action — these still require correct subject agreement.
| Tense | Structure | Example |
|---|---|---|
| Simple Present | Subject + base verb (+s/es) | She works here. |
| Present Continuous | is/am/are + verb-ing | She is working. |
| Present Perfect | has/have + past participle | She has worked here for 3 years. |
| Simple Past | Subject + past verb | She worked yesterday. |
| Future Simple | will + base verb | She will work tomorrow. |
"A/an" are indefinite articles (used for non-specific, first-mention nouns); "the" is the definite article (used for specific, already-known nouns). Use "an" before a vowel sound (an hour, a university — note "university" starts with a consonant sound despite the vowel letter).
| Common Pairing | Correct Usage |
|---|---|
| different from | not "different than" |
| married to | not "married with" |
| angry with (a person) | angry about (a situation) |
| arrive at (a building/point) | arrive in (a city/country) |
Conjunctions join words, phrases, or clauses. Coordinating conjunctions (and, but, or) join equal elements; subordinating conjunctions (because, although, since) join a dependent clause to an independent one. A common error is pairing conjunctions incorrectly, like using both "although" and "but" in the same sentence ("Although he was tired, but he finished the work" — incorrect; drop one).
