MOST can refer to the largest in number or amount:
eg Who do you think will get (the) most votes?
But THE can be left out in informal British English.
MOST can also be used as an adverb meaning VERY:
eg It was most kind of you to meet me.
Now there’s a sentence whose pattern is not rare, and I am not able to figure out the meaning; could you help me?:
He is most recognized for his conduct and his constant position on the “moral high ground” in his fight, as a “shepherd” of his people, against the opium trade in Guangzhou.
I’m not sure whether this sentence is ambiguous: does MOST mean his conduct and his constant position are the most recognized compared with his other qualities? or does MOST mean he is highly (=very) recognized so?
