I wonder if I can use 'less' as an adjective; for example:
Tom has less food than Harry.
....But if the noun is countable, use 'fewer': 'Tom has fewer sausages than Harry.'
What about 'lesser', can I use it in that sentence? "Tom has lesser food than than Harry" or should I necessarily use "amount" , "Tom has lessr amount of food than Harry." ??
lesser is an adjective , so why can't we use it before a noun like 'food'?
