A common mnemonic to remember the difference between gerunds and to-infinitives in English is "STOP" - Subject + To-infinitive + Object = Purpose.

Remembering this simple rule can help differentiate between gerunds and to-infinitives in sentences. **

One common mnemonic device for remembering the difference between gerunds and to-infinitives is the phrase "Remember, regret, and stop."
