Expert writing Tips
Best practice
In formal reports, consider placing this phrase at the beginning of a sentence to immediately establish the reason for the subsequent actions.
Common error
Writers sometimes mistakenly say "because time is small" or "because time is little" when they mean the duration is insufficient. While 'time' can be 'short' or 'limited', it is rarely described as 'small' in this context. Stick to "because time is short" or "since time is limited" to ensure natural phrasing.
