What's the difference between presume and surmise?

Presume


Definition:

  • (v. t.) To assume or take beforehand; esp., to do or undertake without leave or authority previously obtained.
  • (v. t.) To take or suppose to be true, or entitled to belief, without examination or proof, or on the strength of probability; to take for granted; to infer; to suppose.
  • (v. i.) To suppose or assume something to be, or to be true, on grounds deemed valid, though not amounting to proof; to believe by anticipation; to infer; as, we may presume too far.
  • (v. i.) To venture, go, or act, by an assumption of leave or authority not granted; to go beyond what is warranted by the circumstances of the case; to venture beyond license; to take liberties; -- often with on or upon before the ground of confidence.

Example Sentences:

  • (6) Recently, we have designed a series of simplified artificial signal sequences and have shown that a proline residue in the signal sequence plays an important role in the secretion of human lysozyme in yeast, presumably by altering the conformation of the signal sequence [Yamamoto, Y., Taniyama, Y., & Kikuchi, M. (1989) Biochemistry 28, 2728-2732].

  • (16) Presumable this medium was modified repeatedly after its introduction in bacteriology in 1918 by Gassner.

  • (18) Treatment of bacterial cells with inhibitors of gyrase at high concentration leads to relaxation of DNA supercoils, presumably through interference with the supercoiling activity of gyrase.
  • (19) Compared with Sheehan's series in England, it was found the incidence of post-partum hypopituitarism in Okayama was presumably less than in England.
  • (20) In addition, we have shown that long-lived, presumably non-senescent, strains do not arise by suppressor mutation, but lose senescence plasmid DNA by another mechanism.

Surmise


Definition:

  • (n.) A thought, imagination, or conjecture, which is based upon feeble or scanty evidence; suspicion; guess; as, the surmisses of jealousy or of envy.
  • (n.) Reflection; thought.
  • (v. t.) To imagine without certain knowledge; to infer on slight grounds; to suppose, conjecture, or suspect; to guess.

Example Sentences:

  • (1) Taken together, the mutational data allow a functional map of the recognition surface to be constructed and the physical nature of some of the specific interactions that stabilize the antibody-antigen complex to be surmised.
  • (2) Thus, BMIPP is surmised to be able to depict fatty acid metabolism in in vivo myocardial imaging.
  • (3) We surmise that reduction in pulmonary artery perfusion which occurs in pulmonary embolic disease alters the integrity of the alveolar (and possibly bronchiolar) epithelium.
  • (4) We have concluded that renal injuries should be classified by type and extent rather than by etiology, that the extent of injury should be determined and not surmised, and that the management of renal trauma is a function of the extent of injury and the over-all status of the patient.
  • (5) Thus, it is surmised that swine cells are more suitable than rat cells concerning insulin receptor binding and action studies.
  • (6) It was, therefore, surmised that both hypertension and hyperlipidemia would be two of the important factors in inducing the lesions in the cerebral arteries, but although such factors would be coordinative, hypertension might be more important in the process of damaging the cerebral arteries and leading to their degenerative changes.
  • (7) Although these bodies are not viral elements, it is surmised that they may be virus associated and consequently possibly related to the etiology of this tumor.
  • (8) However, the results for TP indicated that prior aquation was not required for protein binding, and we could surmise that binding of TP to protein proceeds via a direct nucleophilic attack.
  • (9) Royles also had to endure more or less the entire committee laughing at him openly when he boasted about consultants' high levels of job satisfaction, something the chuckling Mps surmised might be caused by their stellar pay.
  • (10) Inasmuch as both isoproterenol and prostaglandin E1 increase cyclic AMP content, one can surmise that cyclic AMP is involved in the stimulation of NGF mRNA accumulation.
  • (11) Since drug elimination is intimately associated with physiologic properties that are well described among species, it seems reasonable to surmise that drug elimination can be scaled among mammals.
