## Definition

to become very interested in an idea or to stay close to a person because you find them useful or interesting.

For teachers: to attach oneself to someone or something, often suddenly or with great interest. The verb is transitive and typically implies an opportunistic or intense focus on the object.

## Examples

- She tends to latch onto every new fashion trend she sees.
- Some people at the party latched onto the host and wouldn't let him talk to anyone else.
- Investors were quick to latch onto the startup's promise of high returns, ignoring the significant risks associated with the emerging market.

## Pitfalls

- Not "He latched to the idea." but "He latched onto the idea." — The phrase requires 'onto' or 'on to' rather than just 'to'.

## Usage notes

- The object is usually a person, a concept, or a specific piece of information.
- Teaching tip: Use the physical image of a door latch to help students visualize the 'locking' or 'attaching' aspect of the figurative meaning.
