Core Grammar Rules

4 Key Patterns
1

run the risk of & be at risk of

Use these phrases to talk about possible danger or harm. Always follow them with a noun or an -ing form. Never use the base form of the verb after these phrases.

Example 1: Drivers without insurance run the risk of heavy fines.
Example 2: Homes beside the river are at risk of flooding in spring.
2

stand to

Use this phrase to talk about a result that will probably happen. Always follow it with the base verb. It is mostly used with the words lose or gain.

Example 1: Without proper insurance, homeowners stand to lose their savings in a storm.
Example 2: Small farms stand to gain from the new flood insurance scheme.
3

be liable to / be prone to / liable for

Use the first phrase with a base verb when an unwelcome event is likely. Use the second phrase with a noun or -ing form for something that often suffers a problem. Use the third phrase with a noun to show legal responsibility.

Example 1: Poorly built bridges are liable to crack in a heavy storm.
Example 2: Coastal areas with high exposure are prone to severe erosion.
4

in the event of & there is every likelihood that

Use the first phrase with a noun phrase to name an event. Use the second phrase with a full sentence clause to show something is very probable. Never use a full sentence after the first phrase.

Example 1: In the event of a fire, guests must leave by the nearest stairs.
Example 2: There is every likelihood that a backup contingency plan will save money.

Key Pattern Example

"In the event of a flood, uninsured families stand to lose everything they own."
