11.3 Grammar Rule Extraction Drills

Compare, Infer, Apply

Grammar-rule extraction is the core DLAB study skill because the test is not about already knowing a real language. You are given unfamiliar examples and asked to infer how the artificial system works, then apply it. This chapter does not claim an official DLAB grammar; it uses original practice-style mini-systems to strengthen the habit of finding rules fast and resisting English defaults.

Drill 1: Word Order

Suppose the invented language uses object-action-person order. The sentence mep talu rin means "Rin sees the stone" (mep = stone, talu = sees, rin = the person Rin). Given dol talu rin where dol means tree, do not force English subject-first order. Infer "Rin sees the tree." The slots, not the English habit, decide who acts.

Drill 2: Modifiers

Suppose color words follow nouns. mep zun = red stone, dol zun = red tree. The noun changed while zun stayed constant, so zun carries the shared property red. If mep kal then appears, the noun is still stone and kal is a new property. The stable element is the noun position; the changing element gives the new attribute.

Drill 3: Negation

Suppose the negative marker follows the action. mep talu no rin means "Rin does not see the stone." A careless reader attaches no to the nearest noun. A strong reader compares the positive and negative sentences, notices the only added element sits after the action, and concludes it negates the verb. Always locate the added piece by comparison, not by proximity.

Drill 4: Agreement-Like Markers

Create a split-cue rule. If the object is plural, mark both the noun and the action: mep talu rin (Rin sees the stone) becomes mepu talu-en rin (Rin sees the stones). Number is signaled in two places at once. This trains you to scan the whole sentence rather than stopping at the first marker you find.

The Practice-Style Rule Card

The Four-Step Routine

1. Label every word or ending you already know. 2. Compare the smallest pair of sentences that differ by one thing. 3. Write the rule in plain English. 4. Apply it to a new sentence before checking the answer. If you skip step 3, you may get one item right by feel and then miss the next item that uses the same rule in a new position.

Timed Discipline

Keep timed grammar sets short but strict: about eight minutes for twelve items. If you cannot name the rule within roughly twenty seconds, switch to elimination, cross off any choice that violates a known example, pick the survivor, and move. With 126 questions and only about two hours overall, a single stubborn item can quietly cost you three easy ones later. The timed phase builds decision discipline; the slow review phase afterward builds the actual rule-learning habit. Run both, and never let a confident guess go un-reviewed, because the next item often reuses that very rule.

Worked Example: Stacking Two Rules

Harder grammar items combine rules, so practice stacking. Keep object-action-person order and color-after-noun, then add a fifth element: a question marker qa placed at the very front turns a statement into a question. From mep zun talu rin ("Rin sees the red stone"), the form qa mep zun talu rin means "Does Rin see the red stone?" Nothing inside the sentence moved; only the front marker was added. A weak reader, seeing a new word, scrambles the order looking for an English question inversion.

A strong reader compares the two sentences, sees the only change is a leading qa, and concludes it flags a question without disturbing the slots.

This is the master move of grammar items: isolate the single element that changed between a known sentence and the new one, and assume everything else is stable. The trap is "helpfully" rearranging the rest of the sentence to match English habits, which introduces errors the examples never supported.

Distractor Design You Can Exploit

Wrong answers in artificial-grammar items are rarely random; they are built from predictable mistakes. Expect a choice that uses English word order, a choice that attaches a marker to the wrong word (the negation-to-nearest-noun error), and a choice that drops a required marker such as a plural or question cue. When two choices both look plausible, the right one is usually the one that honors every known example with no extra rearrangement. Naming these distractor families in review, then re-testing on a fresh stacked example a day later, is what locks the rule in.

One more discipline pays off: never let the English meaning seduce you into ignoring a marker. If a sentence clearly carries a plural cue but the most natural English translation reads singular, the plural cue still wins, because you are decoding the system, not polishing English prose. Candidates lose easy grammar points by smoothing translations into comfortable English and quietly dropping a marker the examples plainly required.
