Softening and stressing (po prostu, tak naprawdę, w ogóle)

Stressing

po prostu — simply, just — the most common way to say that there is nothing more to it.

I simply have no time.
Po prostu nie mam czasu.

tak naprawdę — actually, in reality — introduces the real state of affairs, often against what was assumed.

Actually, I don't like fish.
Tak naprawdę nie lubię ryb.

w ogóle — with nie, not at all; in a question, at all: Czy w ogóle lubisz sport? Its cousin na ogół means generally, on the whole.

I don't understand this text at all.
W ogóle nie rozumiem tego tekstu.
On the whole, Poles eat lunch late.
Na ogół Polacy jedzą obiad późno.

Softening

właściwie — actually, in fact — corrects or qualifies what you were about to say.

przynajmniej — at least.

At least it isn't raining.
Przynajmniej nie pada.

całkiem — quite, fairly before an adjective (całkiem dobry); completely with a verb (całkiem zapomniałem).

In the end

w końcu — finally, at last (after waiting), and also after all when you give a reason: W końcu to nie jest ważne.

He finally came!
W końcu przyszedł!

Here is

oto — here is, this is — presents something: Oto mój nowy samochód. It is a particle, not a verb, so nothing is conjugated.
