I’ve always wondered why open and not opened? and also why in heaven in this case is open and shut. if you see answer n5
it reads a" closed case. it doesn’t add up…

Thanks

Here the words are used in an adjectival sense and in Number 5 clearly this is a verbal constuction to be closed. Consider the expression have an open mind.

Hi there,
I don’t understand clearly about shut and close?
can you help me?
thanks

i don’t understand too, can someone explain to us?

Hi,

There are pairs of verbs like finish/end begin/start/ and this one ‘shut and close’ that have a similar meaning but are used sometimes for certain expressions. You would for example close and shut a door/a window/ but you would only ‘close a discussion’ and not shut it.

Hello! I can’t get meaning of “as it was clearly an open and shut case”, can you explain, please. Thank You.

hi luda :slight_smile: open and shut means a legal case or other matter that is easy to decide or solve

now it’s clear

Hi, Alan.

According to your explanation that

and the fact that you hardly mentioned the word ‘shut’, I suppose that you indicate that CLOSED is the correct answer as it’s an adjective means to be closed. But the given answer is SHUT, so would you like to give a further explanation again? It seems not only my own question, as many friends asked this before.

Thanks in advance.

Hi Ttg,

The expression ‘open and shut case’ is an accepted idiom.

Alan

Hi,

Can this idiom be used in any situation when you talk about some problems that are easy to solve?

Thanks

Hi,

It is possible to use the expression in a general sense as long as there is an element of discussion for and against.
