Kindle a fire, a candle, and leaves

Not a candle. 'Kindle' presumes some kind of kindling.

Thank you!

What do you mean ? Do you mean "kindle"implies something is easily kindled?

I think "kindling" is any highly flammable substance (traditionally charred cloth, when starting a fire with flint and steel), and "to kindle" is to cause the "kindling" to catch on fire. The kindling is then used to light something on fire that cannot be ignited with a simple spark, such as small sticks, then large sticks, and eventually logs. Thus, it is not a good application of the word to kin

Do you mean "kindle"implies something is easily kindled? -- No, I think it usually needs kindling (n):

Thanks a lot. So for candle, what word should I use? Ligth a candle? Ignite a candle?

You light a candle.

Thank you

You can also light a fire, start a fire, or even "get a fire going."

Thank you.
