Idiomatic Prepositions

Idiomatic prepositions are fixed prepositions that follow certain verbs, adjectives, or nouns. Unlike prepositions of place or time, these combinations cannot be guessed from meaning alone -- you need to learn them as set phrases.

When to Use

When a verb requires a fixed preposition: "The price of the flat depends on the location and floor level."
When describing someone's role or duty: "The class monitor is responsible for collecting the worksheets."
When explaining what something is made up of: "The committee consists of five teachers and two parents."
When stating the cause or outcome of something: "Careless mistakes resulted in a lower score for the examination."
When expressing strong requests or demands: "The residents insisted on having a covered walkway to the MRT station."

How to Form

Verb + Preposition Combinations

These verbs always take a specific preposition. Using a different preposition changes or breaks the meaning.

Verb	Preposition	Meaning	Example
depend	on	to rely on; to be determined by	Our plans depend on the weather.
consist	of	to be made up of	The test consists of three sections.
insist	on	to demand firmly	She insisted on paying for the meal.
result	in	to cause or lead to	The heavy rain resulted in flooding along the road.
agree	with	to share the same opinion as someone	I agree with you on this matter.
agree	to	to accept a proposal or plan	They agreed to the new arrangement.
agree	on	to reach a decision together	We agreed on a date for the outing.
complain	about	to express dissatisfaction	He complained about the noise from the construction site.
apologise	for	to say sorry for something	She apologised for arriving late to the rehearsal.
succeed	in	to achieve something	He succeeded in qualifying for the national team.

Adjective + Preposition Combinations

These adjectives always take a specific preposition when followed by a noun or gerund.

Adjective	Preposition	Meaning	Example
responsible	for	having a duty for	The prefects are responsible for maintaining order during assembly.
familiar	with	having knowledge of	Are you familiar with the rules of this competition?
capable	of	having the ability to	She is capable of solving the most challenging problems.
different	from	not the same as	Life in the city is different from life in the countryside.
satisfied	with	pleased or content with	The teacher was satisfied with our group presentation.
proud	of	feeling pride about	We are proud of our school's achievements.
aware	of	knowing about	Students should be aware of the examination schedule.
grateful	for/to	thankful for something / to someone	I am grateful for your help. I am grateful to my teacher.

Noun + Preposition Combinations

Some nouns also require fixed prepositions.

Noun	Preposition	Example
reason	for	What is the reason for the delay?
solution	to	We need to find a solution to this problem.
effect	on	Pollution has a harmful effect on the environment.
increase	in	There has been an increase in the number of participants.
advantage	of	One advantage of public transport is that it reduces traffic congestion.

Key Rules

Fixed combinations cannot be swapped: You must say "depend on", not "depend of" or "depend in". There is no grammar rule to predict which preposition goes with which word -- these are memorised as fixed phrases.
Same verb, different prepositions, different meanings: Some verbs change meaning with different prepositions. "Agree with a person" (share the same view), "agree to a plan" (accept), and "agree on a topic" (reach consensus) are three distinct meanings.
"Different from" is the standard form: In Singapore English examinations, use "different from", not "different than" or "different to". "This hawker centre is different from the one near my home."
"Consist of" never takes "consist in" or "consist on": The phrase is always "consist of". Also note that "consist of" is never used in the passive voice -- you do not write "is consisted of".
"Responsible for" vs "responsible to": "Responsible for" means having a duty to handle something. "Responsible to" means answerable to a person. "The head prefect is responsible for the duty roster and responsible to the discipline master."
Gerunds follow prepositions: When a verb comes after a preposition, it must be in the -ing form (gerund). "She apologised for being late" (not "for be late" or "for was late").

Common Mistakes

Wrong	Right	Why
The team consists in five members.	The team consists of five members.	"Consist" always takes "of"
She is responsible of the project.	She is responsible for the project.	"Responsible" takes "for"
This book is different than that one.	This book is different from that one.	Standard form is "different from"
He depends of his parents for money.	He depends on his parents for money.	"Depend" always takes "on"
The accident resulted from many injuries.	The accident resulted in many injuries.	"Result in" = to cause; "result from" = to be caused by
She insisted in going by herself.	She insisted on going by herself.	"Insist" takes "on"

Clue Words

Verb combinations to memorise:

depend on, consist of, insist on, result in, agree with/to/on, complain about, apologise for, succeed in

Adjective combinations to memorise:

responsible for, familiar with, capable of, different from, satisfied with, proud of, aware of, grateful for/to

Noun combinations to memorise:

reason for, solution to, effect on, increase in, advantage of

Tip: Group these combinations by preposition to help memorise them. For example, all the "of" words: consist of, capable of, proud of, aware of, advantage of. Seeing the pattern makes recall easier during examinations.

Practice Tips

Preposition grouping: Write all the words that take the same preposition on one card. For instance, one card for "of" (consist of, capable of, proud of, aware of), another for "on" (depend on, insist on, keen on). Review the cards regularly before your examination.
Sentence completion drill: Cover the preposition in each example above and try to fill it in from memory. Check your answer immediately. Repeat the ones you get wrong.
Spot the error: When proofreading your compositions, circle every preposition that follows a verb or adjective. Ask yourself: "Is this the correct fixed preposition?" This habit catches mistakes before you submit your work.
Context differentiation: For verbs with multiple prepositions (agree with/to/on, grateful for/to), write three separate sentences using each form. This helps you see the meaning difference clearly and avoid mixing them up.
