observation +‎ -al



observational (comparative more observational, superlative most observational)

  1. (sciences) Based on or pertaining to scientific observation.
    • 1988, Andrew Radford, chapter 10, in Transformational grammar: a first course, Cambridge, UK: Cambridge University Press, page 535:
         An alternative way of defending the proposal to conflate NP MOVEMENT with XP MOVEMENT would be to question the observational adequacy of the claim that NP MOVEMENT only ever has NP constituents as its target. Sentences such as the following (from Radford (1981), p. 210) might be used to support the claim that NP MOVEMENT can indeed ‘raiseʼ constituents other than NP:
      (23) (a)      [AP Rather plump] seems — to be how he likes his girlfriends
      (23) (b)      [PP In Paris] seems — to be where they first met
      (23) (c)      [ADVP A little too casually] seems — to have been how he addressed the judge
      (23) (d)      [CP For the Prime Minister to resign] would seem — to be unthinkable
  2. Pertaining to observation in general.
