When people agree with each other on a certain issue or decision, they are often described as being 'of the same mind'. However, there are several synonyms that can be used in place of this phrase. 'In agreement', 'united', 'in harmony', 'in unison', 'in tandem', 'on the same page', 'aligned', 'of one accord', 'synchronized', 'congruous', and 'like-minded' are all great alternatives. Using synonyms adds variety to your writing and can make it more engaging for your readers. So instead of relying on the same phrases and words repeatedly, try experimenting with different synonyms to inject some freshness and variety into your language.
