Dear teachers...
Could 'colourful' (an adjective) be a verb?
I want to draw a circle and colourful it red.
Many thanks
No, the verb is "to colour" or sometimes "to colour in".
I want to draw a circle and colour it red. This, to me, could mean you want to draw a circle with a red pen OR that you want to draw a circle in any colour, but fill the space within the circle with a red pen.
I want to draw a circle and colour it in in red. This would specifically mean that you wish to fill the space within the circle with red.
