run係咪verb? 係run前面加個to「To run」又係咩意思?

"run" is a verb. "run" alone is a bare infinitive; "to run" means the same, and it's a to-infinitive.

there's no difference between the senses of "run" and "to run", but they are used in slightly different ways:

run (verb) 跑步

a. it's so tiring TO RUN under the hot sun. V.S.
b. he is RUNNING under the hot sun.

run (verb) 經營

2. it's complex TO RUN a business. V.S.
3. he RUNS the family business for his father.

as you can see "run" alone can serve as a verb, but "to run" cannot; "to run" has to use with ANOTHER VERB, such as "is" in (a) and (2) in my examples.

good!
