One Word Substitution
🔒 Log in to trackGovernment systems, studies and word-craft
🔒 Log in to trackGovernment by whom? The stem always names the ruler — match the ruler to the suffix -cracy or the classical root:
- by the people → democracy; by officials → bureaucracy; by the rich → plutocracy; by the nobles → aristocracy; by God/clergy → theocracy; by one → autocracy/dictatorship; by the mob → mobocracy (or ochlocracy); no government → anarchy; rule by a king/queen → monarchy.
Studies and -graphy words: geography (earth's surface), demography (populations), cartography (maps), calligraphy (beautiful writing), hagiography (saints' lives), etymology (word origins), philology (language history). The stem 'study of ___' names the object; the -ology/-graphy suffix names the family.
Speech and writing words form their own tight set — prologue/epilogue (start/end of a literary work), epitaph (tomb inscription), elegy (mourning poem), eulogy (words of praise for the dead), euphemism (mild substitute for a harsh word), soliloquy (talking to oneself), extempore (unprepared). Two overlapping pairs are the classic traps: elegy vs eulogy (both about the dead: mourning vs praise) and epitaph vs epilogue (tomb vs play's end).
Time and frequency words: century (100 years), decade (10), annual (yearly), biennial (every two years), biannual (twice a year), diurnal (daily/by day), nocturnal (by night). The biannual/biennial pair decides itself: -ennial counts years, -annual counts per year.
That-which-cannot-be set: inevitable, incredible, invisible, inaudible, illegible, incorrigible, inexplicable — all 'in-/il- + verb of perception or action'. The stem names the verb ('read' → illegible), so link each to its verb: believe→incredible, see→invisible, hear→inaudible, read→illegible, avoid→inevitable, correct→incorrigible.
Detailed notes
Government words: who rules?
Every government word answers one question: who holds the power? Find the ruler in the stem, then match it.
| Ruled by | Word |
|---|---|
| the people (through elected members) | democracy |
| one person with total power | autocracy / dictatorship |
| a king or queen | monarchy |
| the rich | plutocracy |
| nobles, the upper class | aristocracy |
| a small group | oligarchy |
| officials in government offices | bureaucracy |
| religious leaders, in God's name | theocracy |
| nobody (no government, no law) | anarchy |
Worked example: Government by the wealthy → pluto = wealth → plutocracy.
Speech and writing words
These words about speaking and writing come in confusing pairs.
| Word | Meaning |
|---|---|
| elegy | a sad poem mourning the dead |
| eulogy | a speech or writing praising someone (often after death) |
| epitaph | words written on a tomb |
| soliloquy | speaking one's thoughts aloud when alone (as in a play) |
| extempore | spoken without preparation |
| prologue / epilogue | opening part / closing part of a play or book |
| biography / autobiography | life story written by another / by oneself |
| anthology | a collection of poems or stories |
The three 'dead' words: mourning poem → elegy, praise → eulogy, tomb writing → epitaph. Learn them as a set of three.
Time words
| Word | Meaning |
|---|---|
| annual | once a year |
| biannual | twice a year |
| biennial | once in two years |
| perennial | lasting through the years |
| centenary | 100th anniversary |
| decade / century / millennium | 10 / 100 / 1000 years |
| nocturnal | active at night |
| diurnal | active in the daytime |
Memory tip: -ennial counts years (biennial = every 2 years); -annual counts times in a year (biannual = 2 times a year).
'That which cannot be ___' words
These start with in-, il- or im- (meaning 'not'). The verb in the stem gives the answer.
| Cannot be ... | Word |
|---|---|
| read (handwriting) | illegible |
| seen | invisible |
| heard | inaudible |
| believed | incredible |
| avoided | inevitable |
| conquered | invincible |
| corrected or reformed | incorrigible |
| wiped out or removed (a mark) | indelible |
Trap: illegible (cannot be read) vs ineligible (not qualified). They sound alike but mean totally different things.
How to answer
- Decide the type: government, speech/writing, time, or 'cannot be'.
- Find the key word in the stem: the ruler, the kind of writing, the number of years, or the verb.
- Match it, then check the look-alike pair.
Quick revision
- Ruler decides: people → democracy, rich → plutocracy, officials → bureaucracy, God → theocracy, none → anarchy.
- Dead words: elegy (mourning), eulogy (praise), epitaph (tomb).
- Biannual = twice a year; biennial = every two years.
- Cannot-be: read → illegible, conquer → invincible, correct → incorrigible, avoid → inevitable.
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: Government or rule by ...common3 practice Q
Stem: 'Government by ...', 'Rule by ...', or 'A state with no government'.
- Underline the ruler (people, rich, officials, God, nobody).
- Match to the -cracy or -archy word.
- Reject words whose ruler differs.
Why it works: the first part of each word names the ruler.
Example: Government by a small group of powerful people — (a) oligarchy (b) monarchy (c) democracy (d) anarchy
oligo = few → (a) oligarchy.
Type 2: Speech and literary wordscommon2 practice Q
Stem is about a poem, speech, tomb writing, life story or talking alone.
- Decide what the writing does (mourns, praises, marks a tomb, tells a life).
- Match: mourns → elegy, praises → eulogy, tomb → epitaph, own life → autobiography, alone → soliloquy.
- Double-check the elegy/eulogy pair.
Why it works: the options are usually drawn from this small, confusing set.
Example: A collection of poems by different writers — (a) anthology (b) biography (c) epilogue (d) elegy
Collection → (a) anthology.
Type 3: Time and frequency wordsoccasional2 practice Q
Stem mentions how often (every two years, twice a year) or when (at night, 100th anniversary).
- Note the exact number and unit.
- Apply the rule: -ennial counts years, -annual counts per year.
- For day/night use diurnal/nocturnal.
Why it works: the options differ only in the counting, so precise reading wins.
Example: Happening twice a year — (a) biannual (b) biennial (c) annual (d) perennial
Twice a year → (a) biannual. Biennial is every two years.
Type 4: 'That which cannot be ___' wordscommon2 practice Q
Stem: 'That which cannot be read / seen / conquered / corrected'.
- Find the verb in the stem.
- Recall the in-/il- word built on that verb.
- Watch the sound-alike (illegible vs ineligible).
Why it works: each negative word is built on exactly one verb.
Example: That which cannot be heard — (a) inaudible (b) invisible (c) illegible (d) indelible
Heard → audio → (a) inaudible.
Shortcut tricks
⚡ Ruler-first matching
Underline WHO rules in the stem (people, rich, officials, one, God) and match to democracy/plutocracy/bureaucracy/autocracy/theocracy. The stem hands you the answer's head word.
⚡ Verb-link the negatives
Chain each 'cannot-be' word to its verb: read→illegible, believe→incredible, see→invisible. Stems always quote the verb.
⚡ Dead-word precision
About the dead: praise → eulogy, mourning-poem → elegy, tomb-writing → epitaph. Three cards, three certain marks.
Where students lose marks
Choosing 'astrology' for a scientific study of stars.
Swapping biannual (twice a year) and biennial (every two years).
Using 'elegy' where praise of the dead is asked (that is 'eulogy').
Confusing anarchy (no government) with autocracy (one ruler).
