Expert writing Tips

Best practice

Avoid using the phrase "once later" in formal writing. Opt for clearer and more grammatically accepted alternatives such as "at a later time" or "subsequently".

Common error

Using "once later" can create ambiguity because it mixes the sense of 'once' (meaning at a specific point) with 'later' (meaning at a subsequent, unspecified point). Replace it with a term that clearly defines when the event occurred, such as "afterward" or "subsequently".
