Choose the words that best reflect how certain you are. If you are certain that something is true, you can probably state the facts in just a simple sentence following the basic pattern of subject + verb + object.
| Specimen A never grows as quickly as specimen B. |
If you think something is true but cannot prove it beyond all doubt, your words need to reflect this.
| It is almost certain that specimen A can never grow as quickly as specimen B.
This evidence indicates that specimen A will never grow as quickly as specimen B.
It appears that specimen A will never grow as quickly as specimen B. |
If you have an idea about which you are uncertain, use an expression similar to one of the following.
| It is possible that specimen A will never grow as quickly as specimen B.
It may be that specimen A will never grow as quickly as specimen B. |
Nevertheless, establish as much certainty as possible. For more examples of hedging as well as explanations of why it is best kept to a minimum, see
