Can I sell staked ETH?

I've been hearing a lot about staking ETH recently and I'm quite interested in it. But I'm a bit unclear about some aspects. Could you possibly clarify for me? Specifically, I'm wondering if it's possible to sell staked ETH? I've read that staking involves locking up my coins for a certain period of time to earn rewards, but I'm not sure if there's a way to liquidate my stake before the locking period ends. Would I be able to sell it if I needed to? And if so, how would the process work? I'd really appreciate your insights on this matter.
