早就 (zǎo jiù) — use 早已 for emphasis on the long duration before now, while 早就 emphasizes a past expectation or realization.

Imagine a sun rising '早' (zǎo) in the morning, and then picture an old grandfather saying '已' (yǐ) — 'already' — about how long it has been since he saw the sunrise. Together, they remind you that something has been the case for a long time, just like the sun that's always been there.

Be mindful that 早已 is often used in a more formal context and might not be suitable for casual conversation. Common collocations include '早已知道' (known for a long time) or '早已成型' (shaped long ago). Avoid using it in a context that suggests recent events.

While 早已 is not specifically listed in HSK levels, it connects with other time-related phrases and adverbs. Students should focus on understanding the context of time expressions to use them effectively in conversation.

In Chinese culture, recognizing the passage of time and the importance of history is significant. The phrase 早已 often appears in discussions about traditions or long-standing customs that have been in place for generations.

Learners often confuse 早已 with just 已经 and use them interchangeably, which can lead to misunderstandings. For instance, saying '我早已吃了早餐' (I already had breakfast) might suggest it happened long ago, which could be misleading if it was just this morning.
