Question

What is meaning of phrase "No expense is spared" ? ,it means "more expense" or " No expense"? ?

Answer 1

It means that something will be done in spite of any expenses associated with it.  

Answer 2

"No" is a negative. It means, therefore, that there is not any expense not 'spent'.

Reverse the words 'no' to 'every' and 'spared' (saved/withheld/not used) to 'used' and you have: "Every expense is used".

But in this case 'expense' usually means 'resource', not just money.

So the saying means, "Every resource is used"/"Nothing is held back in reserve for this purpose".

Answer 3

It means that there is no budget, no limit to how much to spend. Everything must be the best. Lavish. Extravagant.

Example - For the President's 75th birthday party, no expense was spared. Everything, from the food to the entertainment and decoration, was lavish and extravagant.
