Understanding Dictionary Order: Arranging Words Alphabetically
Arranging words in the order they would appear in an English dictionary requires comparing them letter by letter from left to right. When words share a common prefix, we look at the letters that follow the prefix to determine their relative position.
Let's look at the given words and their corresponding numbers:
- Submerse
- Sublimity
- Submerge
- Submit
- Submarine
All the words start with the prefix "Sub". We need to compare the letters that come after "Sub" for each word.
- Submerse
- Sublimity
- Submerge
- Submit
- Submarine
Comparing the 4th letter, we have 'm', 'l', 'm', 'm', 'm'. According to alphabetical order, 'l' comes before 'm'. So, the word "Sublimity" (2) will come first.
Now let's consider the remaining words, all starting with "Subm": Submerse (1), Submerge (3), Submit (4), Submarine (5).
We compare the 5th letter:
- Submerse
- Submerge
- Submit
- Submarine
Comparing 'e', 'e', 'i', 'a'. The letter 'a' comes first alphabetically. So, "Submarine" (5) is the next word in the dictionary order.
Now we compare the words starting with "Subme": Submerse (1) and Submerge (3).
We compare the 6th letter:
- Submerse
- Submerge
Comparing 's' and 'g'. The letter 'g' comes before 's'. So, "Submerge" (3) is the next word.
Following "Submerge" (3) is "Submerse" (1).
Finally, the last word remaining is "Submit" (4).
Therefore, the correct dictionary order of the words is:
- Sublimity (2)
- Submarine (5)
- Submerge (3)
- Submerse (1)
- Submit (4)
The sequence of numbers representing the correct order is 2, 5, 3, 1, 4.
| Original Order No. | Word | Step 1: 4th Letter | Step 2: 5th Letter | Step 3: 6th Letter | Final Dictionary Order |
|---|---|---|---|---|---|
| 1 | Submerse | m | e | s | 4th |
| 2 | Sublimity | l | i | m | 1st |
| 3 | Submerge | m | e | g | 3rd |
| 4 | Submit | m | i | t | 5th |
| 5 | Submarine | m | a | r | 2nd |
Comparing the final dictionary order to the original numbers:
- 1st word: Sublimity (2)
- 2nd word: Submarine (5)
- 3rd word: Submerge (3)
- 4th word: Submerse (1)
- 5th word: Submit (4)
The correct sequence of numbers is 2, 5, 3, 1, 4.
Revision Table: Key Concepts for Dictionary Order
| Concept | Explanation |
|---|---|
| Alphabetical Comparison | Compare words letter by letter from beginning to end. |
| Prefix Handling | If words share a prefix, compare the letters immediately following the prefix. |
| Letter by Letter | Continue comparing the next letter until a difference is found or one word runs out of letters. |
| Shorter Word Rule | If one word is a prefix of another (e.g., "cat" and "catalog"), the shorter word comes first. (Not applicable in this specific question). |
Additional Information: Practicing Alphabetical Word Arrangement
Mastering dictionary order and alphabetical arrangement is a fundamental vocabulary skill. It helps in using dictionaries, indexes, and sorting lists. Practice with sets of words that have similar prefixes or suffixes to build proficiency. Pay close attention to each letter's position in the alphabet.
For example, arranging words like "apple", "apply", "application", "applaud":
- All start with "appl".
- Compare 5th letter: apple, apply, appli, appla.
- Order of 5th letters: a, e, i, y.
- Resulting order: applaud, apple, application, apply.
Regular practice improves speed and accuracy in solving dictionary order questions, which are common in various tests.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :

One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
