Escapes Saab, oddly blocking Tulla strip (4,4)
I believe the answer is:
runs away
'tulla strip' is the definition.
I can't judge whether this definition defines the answer.
'escapes saab oddly blocking' is the wordplay.
'escapes' becomes 'runway' (I can't explain this - if you can you should believe this answer much more).
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'blocking' is an insertion indicator.
The alternating letters of 'saab' are 'sa'.
'runway' going around 'sa' is 'RUNS AWAY'.
Can you help me to learn more?
(Another definition for runs away that I've seen is " Takes flight".)
