You’re sitting in a ‘problem solving’ meeting and want to put in your two cents. Accepting ideas presented or given is simple especially because you’re basically agreeing: Phrases like: “Yes, that’s a good/great idea.” “Well, that’s (certainly/definitely) worth a try/go” “That sounds like a good idea/good to me.”
The difficulty comes when you disagree or at least have reservations about the suggestion(s) given and want to raise objections. It goes without saying that (a bit of) ‘diplomacy’ is crucial so as not to hurt anybody’s feeling.
So here goes:
“Yes, but … (what about trying ……?)”
“That might be all right but (could/n’t we …?)”
“It’s a good idea but (what if we do/did ….?)”
“I’m afraid*, I’m not so sure about that because ..”
You may want to suggest an alternative by using one of the ‘suggesting phrases’ in brackets.
*Notice how ‘I’m afraid’ is often used to soften the blow.
