When two verbs meet, there are three possible situations: 1. The second verb needs an -ing ending, e.g. I enjoy dream ing . 2. The verbs need "to" in between them, e.g. I want to stay at home today. 3. The verbs stay themselves, needing nothing to add, e.g. We can help you! Some verbs take an -ing ending at one situation, and to at another. The meaning is different in each case. Compare: She stopped swimming and took some rest. While he was hiking through the forest, he noticed a beautiful lake, so he stopped to swim.
