See an excellent answer to almost exactly this question on Peter Baron's superb Philosophical Investigations site. Surprised not to see Intuitionism covered, but a quality essay, with comments from the marker.
To what extent is ethical language meaningful? 
The examiner reported:
There were some very good responses to this question; it clearly caught the imagination and abilities of some candidates and many of the best answers in this unit came from this question. Some candidates were positively enthused by discussing ethical language and did so with great flair.
Candidates were able to make links and cross-references to the problems of religious language and were able to make connections between these approaches to language.
Most answers were not poor but they tended to trot out the pre-prepared answer and therefore appeared (relatively) pedestrian.
There were no common errors or misconceptions.
