☆ careful 注意深い
If you are careful, it means that you give lots of attention to what you are doing in order to avoid making mistakes. When we add the suffix, “-ful” to a word, you can imagine that the person or thing is “full” of the original word. So in this case, full of care. Other words like this are helpful, playful, and beautiful.
So, do you know the suffix that is the opposite of “-ful”? Of course you do. It is “-less.” So for today’s word, “careful” becomes “careless” to describe someone who is “less” care; without care. Some other “less” words are for example, aimless, bottomless, and heartless.
