The Free On-line Dictionary of Computing (30 December 2018):

strict evaluation

   Call-by-value evaluation order is sometimes called "strict
   evaluation" because, in a sequential system, it makes
   functions behave as though they were strict, in the sense
   that evaluation of a function application cannot terminate
   before evaluation of the argument.  Similarly, languages are
   called strict if they use call-by-value argument passing.

   Compare eager evaluation, lazy evaluation.
