14a) switching halves, New Zealander means to collaborate on a website (4). The answer is clearly KIWI or WIKI and I think it's the former but i'm only learning this stuff and not sure of the correct reading of the clue construct / grammer, in this regard.
I uderstand the word 'play' per se but how does the clue make it clear which way round the answer is ? sorry to be a numpty but then I can put this crossword away.
The first definition (New Zealander) gives you Kiwi. "Switching halves" comes before this, so turn it into Wiki which gives you the second definition which is the answer that you require.
