Right sentence using a verb in the subjunctive mood and then explain how you recognize the use of the subjunctive mood
I suggest that he make a decision soon.
In this sentence, the verb "make" is used in the subjunctive mood.

In this case, the sentence expresses a suggestion for someone to make a decision in the near future. The use of the subjunctive mood is recognized by the base form of the verb ("make") without any conjugation changes (e.g., no "s" or "es" added for the third person singular).
