Stative verbs are verbs that express a state rather than an action. They usually relate to thoughts, emotions, relationships, senses, states of being and measurements. These verbs are not usually used with ing in progressive (continuous) tenses even though they may take on time expressions such as now and at the moment. We use the simple tenses for them.
However, there are some verbs that look like they should be stative, but may appear in the ing form. These verbs differ in meaning to the stative verbs.
