Specific action verbs are verbs that are specific to the action you are describing. Think about how comprehension in conversation works.

In order to derive meaning from a sentence, a listener has to recognize each word as it's spoken, derive significance of each word by comparison to the context of the other words in the sentence and then compare the meaning of the sentence to the context of all the sentences that came before and possibly the context of the conversation, context of the relationship, nonverbal queues, the culture of the speaker as well and perhaps the culture at large.

Ideally, a speaker makes this process as seamless and organic as possible.

Too bad then so many speakers complicate this process by speaking with general-use verbs.

"Go to the store and get me some whisky. When you get home, go do your homework. We need to go to early to the train station. That dancer we got for the party is not going to get there on time if we don't go do what we need to get done."

Let's breakdown the third sentence, 'We need to go early to the train station.'

As you read that sentence, ask yourself when do you begin to form an image of the action. Most likely, you don't see anything with your imagination until you read the words 'train station'. Only at that point can you go back and understand the intended, relative meaning, of the verb 'go'. Only at the end of the sentence do you gain any comprehension.

This can be somewhat manageable in written communication. Send someone an SMS message with lots of general-use verbs and they will probably be fine. They can riddle out your meaning at their leisure.

But in spoken conversation or storytelling general-use verbs can overwhelming a listener comprehension. In conversation, there's little time at the end of sentences to riddle out the meaning of the whole sentence before another sentence begins. If as we talk, the listener is suffering under such conditions, they are likely to just nod their head as their mind drifts off to other topics.

However by using specific action words we can smooth and speed comprehension.

Let's try to reword our sentence.

'We need to walk to the train station early.'

I think you will see that's much better. You begin to form an image of action as soon as you get to the word 'walk'. You may not know where yet but you got an idea. By the time you hear the words, 'train station' you are in complete comprehension. Using specific action words makes it easier and more fun to listen to you speak.

Try to use as specific action-verbs as you can.
