Definition of presume on

The phrase "presume on" derives from the verb "presume," which initially appeared in Middle English in the 14th century. The origin of the word "presume" can be traced back to the Old French word "presumer," which meant "to promise" or "to anticipate." The original meaning of "presume" was closely related to the idea of making assumptions or beliefs without sufficient evidence or proof. Over time, the meaning of the word evolved to include notions of overstepping one's bounds or assuming undue privileges. The phrase "presume on" was coined in the early 17th century and originally meant "to rely too much on" or "to place too great a trust in." Today, it is commonly utilized in a similar way, but with the additional connotation of implying a potential disapproval or adverse consequence due to overconfidence or unfounded expectations. In summary, the expression "presume on" can be traced to the medieval French term "presumer" and has evolved in meaning to reflect the idea of excessive trust or overstepping boundaries, potentially leading to negative outcomes.
