Most and maximum

Yes, they do. 'Maximum' often suggests an externally determined limit while 'most' often suggests a competitive achievement, however.

But, can we use "most" with all kinds of countable and uncountable nouns ?
For example, we can say "The maximum/minimum age at which a person has won this award is 56."
But can we say "The most/least age at which a person has won this award is 56" ?

No, you cannot say the latter.

Okay, thanks MM.

Debpriya De "The maximum/minimum age at which a person has won this award is 56.

This should be "highest/lowest age at which..."

If you use maximum/minimum, it should read "The maximum/minimum age at which a person can win this award is 56."

When has height measurement ever been applied to age? Also, given maximum/minimum in adjectival form means the greatest in (whatever measurement it relates to) and not the greatest possible (as is the case when it is in noun form) surely means the sentence was perfectly valid beforehand.

Slight correction: I said "height measuremen"t but this isn't what I intended. What I should have said was: when has the use of high/low ever been applied to age. Very sorry for not catching that before posting.

Hello,

Can can you say

The lowest/highest age at which one has one the award is.....

THank you

I very much doubt it, I have never heard low/high used with age and it sounds very strange. High/low really should indicate things like height, degree, intensity, i.e. "1 metre high", "high price" and "high temperature". Surely minimum/youngest and maximum/oldest are valid though:
The minimum/maximum age in which one has won the award is..
The youngest/oldest age in which one has won the

Most means slightly short of or not quite accomplished

e.g most of them agrees

Whereas, maximum means the largest possible quantity

e.g maximum pressure
