can u give me the exact usage for the following word?
(NOT A TEACHER) You may wish to know that "presumably" is often used as a so-called "sentence adverb" that "modifies" the whole sentence: She came to the United States when she was 20 years old. She is now 60 years old. PRESUMABLY, SHE SPEAKS ENGLISH VERY WELL BY NOW. (Of course, I don't know. I have never spoken with her. I just presume -- guess -- that anyone who lives here for 40 years is going to learn the language, but -- of course --I could be wrong. Maybe she has continued to speak only her native language and has no desire to learn English. That is the reason that we should be careful before we "presume" something.)
