A user wrote in with a question about these two words. Is there a difference? Yes, there is: chiaro is an adjective, and chiaramente is an adverb. But that’s the simple answer.
Language is in constant flux, and chiaro has various meanings, just as “clear” in English does. And this adjective has come to take on the job of an adverb in certain contexts, as Marika mentions in her lesson on adverbs.
"Non fare troppi giri di parole, parla chiaro".
"Don't beat around the bush. Speak plainly."

As a matter of fact, dictionaries list chiaro as both an adjective and adverb, but as an adverb, it's used only in certain circumstances, with certain verbs.
What’s the difference between parlare chiaro and parlare chiaramente?
Well, sometimes there isn’t much difference.
Del resto la relazione del mio collega di Milano parla chiaro.
Moreover, the report from my colleague in Milano is clear.

In the example above, the speaker could have used the adverbial form to mean the same thing.
Del resto la relazione del mio collega di Milano parla chiaramente.
Parlare chiaro has become an idiomatic expression — un modo di dire. It gets the message across very clearly. It implies not using flowery language, wasting words, or trying to be too polite. But parlare chiaramente can have more to do with enunciation, articulation, ormaking oneself understood. So, sometimes parlare chiaro and parlare chiaramente can coincide, but not necessarily.
Apart from this modo di dire, the adjective and adverb forms are used a bit differently in grammatical terms.
Since chiaro is an adjective, it normally describes or modifies a noun. To be correct, then, we often use è (it is).
È chiaro che non lo deve sapere nessuno perché il marito è gelosissimo.
It's clear that no one should know, because her husband is very jealous.

Chiaro may be used by itself with a question mark to ask, “Is that clear?”
E non sono tenuto a spiegarti niente, chiaro?
And I'm not obliged to explain anything to you, is that clear?

The adverb chiaramente, on the other hand, can stand alone before or after another clause or can be inserted just about anywhere in a sentence.
Natoli ha chiaramente bisogno di glutine, eh.
Natoli clearly needs gluten, huh.

Using chiaro, Paolo could have said:
È chiaro che Natoli ha bisogno di glutine.
It’s clear that Natoli needs gluten.
But chiaro has a special in-between meaning when it’s used in place of an adverb with verbs such as parlare (to speak) and vedere (to see).
Finché non ci ho visto chiaro la tengo io.
Until I've seen things clearly I'm keeping it.

Although we have translated it with an adverb, we could also say:
Until I get a clear picture of things, I’m keeping it.
Look for sentences with either chiaro or chiaramente and try switching them, making the necessary changes. Doing a search on the video tab will give you plenty of examples.
