"More recommendatory" refers to a strong recommendation or endorsement of something. The antonyms for this phrase can vary depending on the intended meaning. If we want to convey the opposite of recommending something, we can use words like "discourage," "dissuade," or "deprecate." On the other hand, if we want to express a weaker endorsement or suggestion, we can use words like "caution," "suggest," or "propose." Additionally, we can use antonyms that express a lack of conviction or certainty, such as "hesitant," "lukewarm," or "reluctant." In any case, the choice of antonyms depends on the context and purpose of the communication.
