Common Mistakes to Avoid When Using the Idiom “latch onto”

When it comes to using idioms, it’s important to understand their meanings and how they are used in context. However, even when we think we know an idiom well, there are common mistakes that can trip us up. This is especially true for the idiom “latch onto”, which has a few nuances that can be easy to overlook.

One mistake people make when using “latch onto” is assuming it always means to grab hold of something tightly. While this is one definition of the phrase, it’s not the only one. Depending on the context, “latch onto” can also mean to become interested in or fixate on something. For example, someone might say “I latched onto yoga after my first class” meaning they became very interested in practicing yoga regularly.

Another common mistake with “latch onto” is using it incorrectly with prepositions. The correct preposition to use after “latch onto” depends on what follows next in the sentence. If you’re talking about an idea or concept, you would use “onto”. For example: “She latched onto the idea of starting her own business.” However, if you’re talking about a physical object or person that someone has grabbed hold of tightly, you would use “on”. For example: “The child latched onto his mother’s leg and wouldn’t let go.”

Finally, another mistake people make with this idiom is overusing it as a crutch instead of finding more creative ways to express themselves. While there’s nothing wrong with using idioms from time to time (they can add color and personality to our language), relying too heavily on them can make your speech or writing sound clichéd or unoriginal.
