Can you please explain differences in following phrases:
- I am thinking
- I thinking
- I think
- I have been thinking
I am thinking This is present tense. You currently thinking at this precise moment.
I thinking This is not the correct usage of English. I would presume it was heard as the incorrect version of the above.
I think This version precedes your opinion. For example, "I think there will be further welfare cuts in the budget."
I have been thinking This variant is past-tense. You have considered a topic and are reflecting upon it.
