Is there ever a difference between descriptions of frequency and the present tense?
For example, is there a difference between "I speak English." (referring to frequent speaking of English) and "I speak." (in present tense, as you might see in a first-person narrative)?
If so, what is it? If not, why isn't there a difference between the two?
I apologize for my vagueness in use of the word "difference". I'm asking for any sort of difference, even at the most general level, in how the two are used in a sentence.
