1. My grandfather was in hospital.

Question

2. My grandfather was in the hospital.
3. My grandfather was hospitalized.

(What does #1 and #2 mean? Are both #1 and #2 the same? Does #1 or #2 mean #3? He may have visited a patient. Don't you think so?)

Answer 1

#1 is the British English way to state this idea.

#2 is the American English way to state this idea.

#3 means the same as both of the first two.

(If someone were visiting in a hospital, the sentence would be this: My grandfather was at the hospital.)
