[pinguin]

Kova tuuli puhaltaa.

Tuuli puhaltaa kovaa.

Tuuli puhaltaa kovasti.

Which of these are correct and what is the difference between the last two?

Kiitos.

Hard wind blows
Wind blows hard
Wind blows harshly

corrections accepted

The obvious corrections, since you asked for them, would be
"A hard wind blows."
"The wind blows hard."
"The wind blows harshly."

Of course, "kovasti" can also mean "a great deal; very much", but I think they all describe pretty much the same thing in the context of wind.

A native speaker would most likely say "On kova tuuli.", "Tuulee kovaa." or maybe even "Tuuleepa siellä!"

Kova tuuli puhaltaa.

Tuuli puhaltaa kovaa.

Tuuli puhaltaa kovasti.

Which of these are correct and what is the difference between the last two?

All of the above are correct. The last one perhaps better lends itself to an interpretation it’s the writer’s subjective assessment of how the wind appears or feels to behave today, instead of just a plain statement of a measurable fact.

A native speaker would most likely say "On kova tuuli.", "Tuulee kovaa." or maybe even "Tuuleepa siellä!"

Kylläpä siellä tuuleekin! (Good grief. I didn’t expect the wind to be quite that hard today.)

Siellä sitten vähän tuulee vissiin? (mild sarcasm, the speaker is probably looking at your hair) (vissiin = one of the “innit?” words of Finnish)

Pikku(i)nen tuuli tuolla ulkona! (pikkuinen used here as an obvious understatement — so much so it doesn’t really even register as one but is instantly interpreted as the opposite meaning: the wind is blowing really awesomely hard right now; definitely not a “tiny wind” at all!)

She loved him harshly.

She loved him hard.

She loved him hardly . . . at all.

Why do baby ducks walk softly?

Because they can't walk at all hardly.

More seriously, I hear kovaa as describing an ongoing physical activity (they're hard at it) but kovasti as more generic and abstract. There are more places you can use kovasti without raising an eyebrow than places you can use kovaa without doing so.

Thus kovaa works for wind, surf, rain, athletics, etc. Not so much for rakastaa but probably for rakastella.

Kovasti works just about everywhere.

Hence my joking examples above.

Tyttö rakasti poikaa kovasti. The girl loved the boy deeply (not harshly).

It doesn't really make sense to say tyttö rakasti poikaa kovaa but for me it brings to mind smirkworthy fragments such as ratsasti . . . kovaa (rode hard) or changing kovaa to kovana, "in a state of hardness." For various reasons neither of these quite fits together correctly but it's still somewhat amusing to me.

Then again I could be completely wrong about all of it.

Tyttö halusi pojan kovaa kovasti.

What about the following:

Älä puhu niin kovaa!
Älä puhu niin kovasti!

Are both acceptable?

What about the following:

Älä puhu niin kovaa!
Älä puhu niin kovasti!

Are both acceptable?

Niin kovaa there means so loud(ly).

Niin kovasti there means so much.

Poika kaipaili kovasti tytön luokse.
