Salad type that’s oddly preceding appetisers (5)
I believe the answer is:
tapas
'appetisers' is the definition.
(I've seen this before)
'salad type that's oddly preceding' is the wordplay.
'salad type' becomes 'pas' (I can't justify this - if you can you should give a lot more credence to this answer).
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'preceding' means one lot of letters go next to another.
The alternating letters of 'that' are 'ta'.
'pas' after 'ta' is 'TAPAS'.
Can you help me to learn more?
(Other definitions for tapas that I've seen before include "Pasta (anag) - Spanish bar food" , "Spanish appetisers" , "Spanish bites?" , "What's served in Spanish bar" , "Spanish appetiser" .)
