状態を表す動詞は、物事がどのようであるか、を表す動詞。State verbsと言います。一方行動を表す動詞をDynamic verbsと呼びます。動詞によってはその両方の役割ができる動詞も。その一方、意味が異なる場合もあります。以下の例文をみてみましょう。
[Dynamic] I am having lunch now. = I am eating lunch now.
[State] I have a car. = I possess/own a car.
[Dynamic] I am seeing my friends in the evening. = I am meeting my friends in the evening.
[State] I see why that is a problem. = I understand why that is a problem.
[Dynamic] The man is weighing the fruit = The man is measuring the weight of the fruit.
[State] The man weighs 75kg. = The man's weight is 75kg.
[Dynamic] I am thinking about my future. = I am considering my future.
[State] I think that is a great idea! = My opinion is that is a great idea.
Other words that can be used in this way are appear, be, cost, expect, feel, fit, hear, imagine, look, smell, and taste.
When you use the dynamic meaning of the verb, you can use both the continuous or the simple form of the verb.
- I am having lunch now. and
- I have lunch every day at the same cafe.
The state meaning of the verb is almost always never used with a continuous form.
- I have a car not
I am having a car.
