Dictionary Order & Alphabet

🔒 Log in to trackStandard question: 4-6 words are given; arrange them as in a dictionary and answer which comes first, second, middle, or last. Practical pipeline:
- Group words by their first letter (usually all share one or two letters).
- Inside a group, repeat by the second letter, then the third — the groups shrink fast.
- Count down to the asked slot: 'third from the left' = the third word in the final order.
Answer options are usually the words themselves; wrong options come from comparing at the wrong position — which is exactly what the split-point method prevents.
Detailed notes
The standard 4-6 word arrangement
This is the topic's workhorse: a list of 4-6 similar words, and one lookup — "which comes third", "which is last", "which comes just after X", "which is second from the right". The method never changes; only the lookup does.
Step 1 — group by the shared stem. Exam words almost always share a long prefix (Stat-, Colon-, Dec-). Find the stem and draw it once; only the letters after the stem matter. Statue, Status, Statute, Stature, Station all share STAT — the fight starts at the fifth letter.
Step 2 — split at the first difference. Line up the words, ignore the common stem, and look at the next letter of each. Sort by those letters. Ties inside a letter move one position deeper. In the STAT family: Station (i) separates immediately; Statue/Status/Statute/Stature all show E/S/E/R at position six, then sort by the seventh where needed.
Step 3 — apply the prefix rule inside ties. When one word is a stem-with-nothing (Colon inside Colonial... but also Decamp family: Decay vs December), remember: exact prefix sorts before its extensions; among extensions, the next letter decides.
Step 4 — number and read. Write the final order as a numbered line, 1 to N, then answer whatever was asked:
- "Third word" → slot 3.
- "Second from the right" → slot N−1.
- "Just after X" → slot of X plus one.
- "Adjacent pair" → two words whose slot numbers differ by exactly 1.
Speed practice pays twice. These questions are pure procedure — the same 30-second routine solves every one. Errors come almost only from mis-comparing one letter pair (mixing up m/n order, reading r before s) or from mis-counting slots ('second from right' vs 'second'). Both are prevented by the numbered line: letters decide the order, numbers decide the answer.
Check with extremes. Before locking an answer, confirm the obvious: the word with the alphabetically earliest deep letter should sit near the left end, the latest near the right end. If your final order violates that instinct, re-scan column two — a transposed pair is the usual cause.
Quick revision
- Strip the shared stem; the battle starts at the first letter after it.
- Prefix (bare stem) sorts before any extension of itself.
- Write the full numbered order, then read the requested slot off it.
- 'Second from the right' = slot N−1; 'just after X' = X's slot + 1.
- Sanity-check: earliest deciding letter at the left end, latest at the right.
Time target. A practiced 5-word arrangement takes 30-40 seconds: 5 for the stem, 15 for the column scan, 10 for the numbered line, 5 for the lookup. If you are past a minute, you are re-sorting in your head — restart on paper; it is faster than a third mental pass.
Types of questions asked
Every way this subtopic shows up in exams — how to recognise it, the formula or logic to use, and a solved example.
Type 1: Arrange and pick the slotvery common2 practice Q
4-6 words; 'which is the Nth word in dictionary order' (from the left).
- Strip the shared stem; sort by the first differing tail letter.
- Write the numbered order 1..N.
- Read slot N and check it against the extreme words.
Why it works: one sort, then a positional lookup.
Example: Arrange Chalk, Charm, Chart, Chase, Chatter. Which is the fourth word?
4th letters: l / r / r / s / t → Chalk, Charm, Chart, Chase, Chatter → fourth = Chase.
Type 2: Prefix vs later-letter battlevery common2 practice Q
The list mixes a bare stem with extensions that fight over a later letter.
- The bare stem sorts before all extensions.
- Extensions sort by the letter right after the stem; ties go one letter deeper.
- Re-scan the deciding column twice — one misread flips two slots.
Why it works: first difference decides, at whatever depth it hides.
Example: Arrange Mystery, Mystic, Myself, Myopia. Which comes first?
3rd letters: s / s / s / o → Myopia first; among the s-words, 4th letters e/t/t → Myself, then Mystery (5th e) before Mystic (5th i). First = Myopia.
Type 3: Extremes and immediate neighbourscommon2 practice Q
'Which comes last / just after X / immediately before Y' — neighbour lookups on the sorted list.
- Sort fully and number the slots.
- 'Just after X' = X's slot + 1; 'immediately before Y' = Y's slot − 1.
- For 'last', only the deepest group's final word matters.
Why it works: neighbours are slot arithmetic on the finished order.
Example: Which comes just after Colony: Colonel, Colony, Column, Colour, Colossus?
Order: Colonel, Colony, Colossus, Colour, Column → just after Colony = Colossus.
Type 4: Counting from the right endcommon2 practice Q
'Second from the right', 'third from the end' — the slot is counted from the back.
- Sort and number 1..N as usual.
- k-th from the right = slot N + 1 − k.
- Convert first, then read — do not count backwards on the raw list.
Why it works: mirror of the slot lookup: the right end is slot N.
Example: Arrange Judge, Judo, Joust, Journal, Jostle. Which word is second from the right?
Order: Jostle, Journal, Joust, Judge, Judo → slot 5 + 1 − 2 = 4 → Judge.
Shortcut tricks
⚡ Slot-count from the left
Once sorted, number the words 1, 2, 3… and simply read the asked position. 'Comes last' = highest position; 'middle of five' = position 3.
Example: Q. Cable, Cabin, Cabaret, Cabbage — which comes third?
Sol. CABA < CABB < CABI < CABL → Cabaret, Cabbage, Cabin, Cable → third = Cabin.
Sort once, count to the slot; never re-compare for each option.
Where students lose marks
Re-sorting mentally for every option instead of fixing one order.
Answering 'third from the right' with the third word from the left.
