Word jumbling and dictionary order for RRB Group D

These questions use everyday words and no arithmetic at all. You arrange words as they would appear in a dictionary, put a set of steps into the order they happen in real life, unscramble a jumbled word, or spot which word cannot be made from the letters of a longer word.

They are some of the quickest marks in the reasoning section, often under 30 seconds each. They are also where careless answers are most common, because they feel too easy to check. A fixed routine for each type fixes that.

The four types at a glance

Dictionary order

Compare the words letter by letter from the left. The first position where the letters differ decides the order. Everything after that position is ignored.

There is one special case. If one word is the start of another (CAR and CARD), the shorter word comes first. Think of it as the shorter word "running out" of letters first.

Worked example 1: Arrange in dictionary order: Rain, Rail, Race, Rack.

• All four start with "Ra". Third letters: i, i, c, c. So Race and Rack come before Rail and Rain.
• Race vs Rack: fourth letters e and k. Race comes first, then Rack.
• Rail vs Rain: fourth letters l and n. Rail comes first, then Rain.
• Order: Race, Rack, Rail, Rain.

Worked example 2: Arrange in dictionary order: Cart, Card, Car, Care.

• "Car" is the start of all the others, so it comes first.
• The fourth letters of the rest are t, d and e. In order: d, e, t.
• Order: Car, Card, Care, Cart.

Meaningful order

Here you arrange words by a natural sequence: the steps of a process, the stages of life, or sizes from small to large. Use the usual order, the one most people would agree on, not the order of your own day.

Worked example 3: Arrange in a meaningful order: 1. Seed 2. Plant 3. Fruit 4. Flower

• A seed grows into a plant. The plant flowers, and the flower becomes a fruit.
• Order: 1, 2, 4, 3.

Worked example 4: Arrange in a meaningful order: 1. Harvesting 2. Sowing 3. Ploughing 4. Selling

• A field is ploughed, then seeds are sown, then the crop is harvested, then sold.
• Order: 3, 2, 1, 4.

Common sequences to know:

• Life stages: infant, child, adolescent, adult, old age.
• Size of places: room, house, city, state, country.
• Education: admission, study, examination, result, certificate.
• Cooking: buying, cleaning, cutting, cooking, serving.

Unjumbling

Look for common letter groups before trying random orders.

• Common endings: -ING, -TION, -ER, -ED, -LY, -ANT.
• Common starts: TR, ST, CH, SH, PR, BR.
• Try placing vowels between consonants. Many short words alternate between the two.

Worked example 5: Unjumble TTIOSNA.

• The letters include T, I, O, N, so try the ending -TION. That leaves S, T, A.
• ST + A + TION gives STATION.

Making words from a word

Every letter of the new word must be in the given word, and as many times as it appears in the new word. A letter that appears once in the given word can be used only once.

Worked example 6: Which word cannot be made from the letters of TEACHER? (a) CHEAT (b) REACH (c) CHAIR (d) TEACH

• Check each option letter by letter against T, E, A, C, H, E, R.
• CHEAT, REACH and TEACH all fit. CHAIR needs an I, which TEACHER does not have.
• Answer: (c).

Common mistakes

• Stopping at the first letter in dictionary order when the words share a start.
• Putting a longer word before its own start (CARD before CAR).
• Ignoring how many times a letter appears when forming words.
• Choosing the order of your own day instead of the usual order.
• Unjumbling in your head. Write the letters down and cross them off as you use them.

Practice set

1. Arrange in dictionary order: Book, Boat, Bold, Bolt.
2. Arrange in a meaningful order: 1. Graduation 2. Admission 3. Examination 4. Study
3. Unjumble: LSOHOC.
4. Which word cannot be made from the letters of STATION? (a) SAINT (b) TOAST (c) NOTES (d) ANTS
5. Arrange in dictionary order: Plate, Plant, Plane, Planet.
6. Which word comes third in dictionary order: Train, Track, Trace, Trade, Trail?
7. Which word cannot be made from the letters of ENGINEER? (a) GREEN (b) REIGN (c) NINE (d) RANGE
8. Arrange in a meaningful order: 1. Adult 2. Child 3. Infant 4. Old age 5. Adolescent

Answers:

1. Boat, Bold, Bolt, Book. Third letters a, l, l, o. Then Bold before Bolt (d before t).
2. 2, 4, 3, 1. Admission, study, examination, graduation.
3. SCHOOL.
4. (c) NOTES. STATION has no E.
5. Plane, Planet, Plant, Plate. Plane is the start of Planet, so it comes first. Planet vs Plant: fifth letters e and t. Plate is last because its fourth letter t comes after n.
6. Trade. The full order is Trace, Track, Trade, Trail, Train.
7. (d) RANGE. ENGINEER has no A. NINE is fine, because ENGINEER has two N's.
8. 3, 2, 5, 1, 4. Infant, child, adolescent, adult, old age.

What to do next

• Practise dictionary order with five-word sets until you can do one in 20 seconds.
• Learn the common sequences above and add two of your own.
• For word formation, always count repeated letters before choosing.
• Revise coding–decoding and number and letter series, which use the same alphabet skills, and see the reasoning plan.
