What about 'lesser', can I use it in that sentence? "Tom has lesser food than than Harry" No. or should I necessarily use "amount" , "Tom has a lesser amount of food than Harry." ? You could say this, but it wouldn't be very natural. One question mark is sufficient.
'Lesser' means 'smaller', 'less important/significant'. It is the antonym of 'greater', not of 'more'.lesser is an adjective , so why can't we use it before a noun like 'food'?
So is 'blue'. Some words don't go with others. 'Lesser' and 'food' form this sort of non-collocation.lesser is an adjective , so why can't we use it before a noun like 'food'?
