Expert writing Tips

Best practice

Use "knew I would" when you want to express a past certainty about a future event or outcome. It adds a sense of inevitability or strong anticipation to your statement.

Common error

Avoid using "knew I will" as it mixes past and future tenses incorrectly. "Knew" indicates a past understanding, so it should be followed by "would" to refer to a future action from that past perspective.
