-see also: think big think 1 (17) - bigness noun (U) USAGE NOTE: BIG WORD CHOICE big, large, great Big and large are both often used to talk about or to talk about the measurements of things or groups, though large is slightly more formal and not so often used of people: That shirt doesn't fit me - it's too big/large. | How big are you round the waist? | a big crowd/company/gap | a large family/city/university. See also fat WORD CHOICE and wide WORD CHOICE. None of these words are used with uncountable nouns for things you can touch: There was a lot of traffic/land /space (NOT big traffic, large land). Great means famous or important for something good, or, when it is used about ordinary people, just extremely nice: Rembrandt was a great painter. | Isn't Max a great guy? See also famous WORD CHOICE. Great used about the size of things or events is mainly found in literary writing or names and means `very large and impressive': The great city of Samarkand. | A great crowd had gathered. | a great banquet | The Great Wall of China. Otherwise great is used very informally of things just to mean extremely good: You look great! | There's a great view from our hotel room. | We had a great time there (=enjoyable, not necessarily long). You would usually use great rather than big to describe the size or extent of things you cannot touch: She showed great courage/talent/ability. | We had great fun. | in great detail. Where both can be used, great is stronger and suggests more importance: It's a big/great pleasure to see you. | great/big problem/opportunity/danger. But note that you usually say a big difference/mistake/argument | It isn't a big deal (informal=It's not serious or important). Note that large (less often great or big) is used with these quantity words: a large amount, number, extent, percentage, volume / area. But note only great is used in: a great deal (=a lot) | at great length | a great height/age
