does treasury and state have to be capitolized?

Question

this are some sentences i'm writing alexander hamiliton was secretary os treasury wat has to be capitoliezed.....and jefferson was secretary of treasury

Answer 1

Yes, they do if they refer to a specific Treasury or a specific State. This is basic English grammar.
Your question has two mistakes or more in it. It should start with the word 'Do' and the word is "capitalized'. Capitol refers to a place, capital is about upper case or lower case.
If your computer has all the upper cases letters, you should practice using them. You may find that you get more respect when you use correct spelling and punctuation.
