When communicating or expressing oneself, we often encounter times when we hesitate to fully disclose or reveal certain information or emotions. In such situations, we often use the phrase "hold something back" to describe our reluctance. However, there are several synonymous phrases that can also convey the same meaning. One may opt to say "restrain oneself", implying a conscious effort to keep withheld thoughts or feelings. Another alternative is "suppress", indicating the deliberate act of controlling or concealing something. Similarly, "conceal", "reserve", and "keep under wraps" all suggest the act of holding back information or emotions, each lending a slightly different nuance to the situation.
