Fiscal budget: spending in real vs nominal terms What does it mean in the context of a budget to “freeze spending in real terms”? And how would this differ from freezing spending in “nominal terms”? 

I am looking to understand how this would be implemented and the broader macro relevance
If there is no inflation then the two phrases would mean the same

But if there is positive inflation, then "freezing spending in nominal terms" would involve spending the same amount of money, and since prices are rising, would involve buying less.  Meanwhile "freezing spending in real terms" would involve spending an increased amount of money corresponding to the increase in prices, with the effect after taking price changes into account of buying the same amount.
