This one paragraph contains a business grammar error. Find and correct it.
Most important is insuring your clients are well informed. Information sent to clients so far has been sparse, and this must improve.
Correction:
Most important is ensuring your clients are well informed.
- Assure means "to give someone confidence."
- Ensure means "to make certain."
- Insure means "to protect against loss."
Examples:
Most important is ensuring (making certain) your clients are well informed.
I want to insure this necklace (protect it from loss) for $5000.
I assure you (give you confidence) that the deadline will be met.
