When we express our hesitation or skepticism towards something or someone, we often use the phrase "have one's doubts." However, there are several synonyms that can enhance our language and provide a wider range of expression.
One possible substitution is "skeptical," which indicates a strong doubt or uncertainty. "Questioning" is another option, which implies critical inquiry and thoughtful consideration. "Dubious" or "uncertain" can convey a lack of confidence in a decision or assertion, while "hesitant" suggests a reluctance to commit fully. Finally, "unsure" or "unsettled" can show a general uneasiness with a situation or idea. These alternative phrases can add nuance and depth to our communication and help us express our thoughts and feelings more accurately.
