Your mom has been so worried about your little brother’s persistent leg pain. “May be it’s his ill-fitting shoe, mom,” you suggest. Your brother’s leg pain disappears with the new, bigger pair of shoes and all is back to normal. Your mom tells you, “Smitha, you know, you hit the nail on the head ?” Now it’s your turn to worry, wondering what she meant.
But worry not. To hit the nail on the head is an idiom which means to be precisely right about something or to spot the cause of a problem, which is close to its literal meaning. Hitting the nail on the exact spot will give the desired result to the carpenter.
You might have hit the nail on the head when you suggested that Jina should not worry about making mistakes while communicating in English for her to get fluency of the language or when you identified the perfect accessories to match your sister’s new outfit and she’s so happy about it.
So, hit the nail on the head and stop worrying!
