how about the word "fly" and "fly high" in latin?

to fly
volare

to fly high
volare alte

does the meaning of "to fly high" and fly high are same?

"to fly high" is the infinitive

If you mean "fly high" as a request or command, then use the imperative.
vola (if addressing one person)
volate (if addressing more than one person)

If you mean "fly high" as a statement, use the indicative.
Latin uses different forms for first, second and third person as well as for
singular and plural, so:
volo -- I fly
volas -- you fly (singular)
volat -- he, she, or it flies
volamus -- we fly
volatis -- you fly (plural)
volant -- they fly

Is this helpful, or just more confusing?

hmm..... then if i use the word of "fly high" for title, the latin is "volare alte"?

volare = to fly
alte = high

Then, What is "the heart that darker than black"

cor obscurior quam nigrum

then, how about, darker than black in latin?

CORRECTION
That should be:
cor obscurius quam nigrum

obscurius quam nigrum

thanks
