One Word Substitution
One word substitution is the skill of expressing a whole phrase or clause in a single precise word, and it is a favourite topic of the ADRE Grade IV General English paper because it tests both vocabulary and understanding at the same time. Instead of saying a person who does not believe in the existence of God, we say an atheist; instead of saying a place where weapons are kept, we say an armoury. The method followed in the Master Book approach is to learn these words in groups by meaning rather than alphabetically, because words of the same family share a common ending and are therefore remembered together. A candidate who learns the common suffixes and the groups they belong to can often work out an unfamiliar word from its ending alone, and this turns a long list into a short set of patterns.
Basic Terms
- One word substitution: a single word used in place of a longer phrase.
- Suffix: an ending added to a word, such as ology, cide, phobia or mania.
- Prefix: a beginning added to a word, such as mono, poly or anti.
- Root word: the base part that carries the main meaning.
- Phobia: an abnormal fear of something.
- Mania: an abnormal love or obsession for something.
Most one-word substitutions are built from a small number of roots and suffixes. Learning the roots allows the candidate to build many words from a single piece of knowledge.
Words for Persons
Many substitutions name a person by what the person does. One who writes books is an author, one who treats the sick is a physician, one who studies the stars is an astronomer, and one who does not eat meat is a vegetarian. Groups such as these are best learned together, because the mind recalls a set more easily than a single item.
Words Ending in ology and graphy
The ending ology means the study of something, as in biology, geology and psychology. The ending graphy means writing or description, as in geography, biography and calligraphy. Recognising these two endings lets the candidate decode a large number of words from their subject matter alone.
Words for Fear and Love: phobia and mania
The ending phobia means fear, as in claustrophobia, a fear of closed spaces, and hydrophobia, a fear of water. The ending mania means a strong love or obsession, as in bibliomania, a love of books. These endings are very commonly tested, and they are among the easiest to remember because the meaning is fixed.
Words Ending in cide and other endings
The ending cide means killing, as in homicide, the killing of a human being, and patricide, the killing of one's father. The ending phile means a lover of something, as in bibliophile. The ending phobe means one who fears, as in xenophobe. Once these few endings are known, a great many words fall into place.
Words for Places, Groups and Qualities
Some substitutions name a place, such as an apiary for a place where bees are kept, and a hangar for a place where aircraft are kept. Others name a group, such as a herd for cattle and a fleet for ships. A third set names a quality, such as brevity for shortness of speech and veracity for truthfulness. The candidate should build a small list in each class.
How This Topic Appears in the Examination
In ADRE Grade IV, APSC and Assam Police English papers this topic appears as a phrase for which the single correct word must be chosen from four options, or as a single word whose meaning must be matched to a phrase. The tested words usually come from the common families, so a candidate who knows the roots and endings has a clear advantage.
Shortcut Methods for Quick Answers
Look for the key word in the phrase and match it to a known root or ending. If the phrase speaks of fear, think of phobia; if of love, think of mania; if of killing, think of cide; if of study, think of ology. Use the process of elimination against the endings. When a word looks unfamiliar, break it into root and ending and read the meaning from the two parts.
Common Mistakes to Avoid
- Confusing words of similar sound but different endings, such as phobia and philia.
- Choosing a word that fits the general sense but not the exact phrase.
- Learning words alphabetically instead of by family, which makes recall slow.
- Ignoring the small words in the phrase that fix the meaning, such as abnormal or one who.
- Mixing up the endings cide and cidal, or ology and logy.
How to Prepare This Topic
- Learn the common roots and endings with their meanings.
- Group the words by family: persons, places, fear, love, killing, study.
- Revise five words from each group every day.
- Practise turning a phrase into a word and a word back into a phrase.
- Finish with a mixed set and keep a running list of new words.
Frequently Asked Questions
How can suffixes help in one word substitution?
Many words share a fixed ending with a fixed meaning, such as phobia for fear, mania for love, cide for killing and ology for study. Recognising the ending often reveals the meaning of the whole word.
What is the difference between phobia and mania?
Phobia is an abnormal fear of something, as in claustrophobia. Mania is an abnormal love or obsession for something, as in bibliomania. The two endings give opposite feelings.
Should I learn one word substitutions alphabetically?
No. Learning them by family and ending is far more effective, because words of the same group support one another in memory and share a common pattern.
How do I decode an unfamiliar one word substitution?
Break the word into its root and ending and read the meaning from the two parts. For example, the ending cide tells you the word has to do with killing.
Which families are asked most often?
Words for persons, places and groups, and words ending in phobia, mania, cide and ology. These few families cover a large part of the questions set.
