Where it comes from

Borrowed from Latin speculātus, perfect active participle of speculor (“to watch, observe, examine, spy”) (see -ate (verb-forming suffix)), from specula (“a watchtower”), ultimately from speciō (“to look at”).

verb speculates · speculating · speculated

  1. intransitive, obsolete To think, meditate or reflect on a subject; to consider, to deliberate or cogitate. It is remarkable that persons who speculate the most boldly often conform with the most perfect quietude to the external regulations of society.
  2. intransitive To make an inference based on inconclusive evidence; to surmise or conjecture. We can speculate that in many instances the sharks are not feeding on their victims, but only in a few cases can we guess what they are doing.
  3. intransitive To make a risky trade in the hope of making a profit; to venture or gamble. Some preliminary legal arrangements were made, but the scheme proceeded no further, as the various local authorities concerned were unwilling to speculate public funds on what was, even at that date, a will o' the wisp.
  4. intransitive To anticipate which branch of code will be chosen and execute it in advance.
