An odd outburst of anger on the way (7)
I believe the answer is:
strange
'an odd' is the definition.
(I've seen this in another clue)
'outburst of anger on the way' is the wordplay.
I cannot really see how this works, but
an anagram of 'anger' is 'range' which is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'way' could be 's' (Compass direction - South) and 's' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for strange that I've seen before include "Extraordinary" , "Abnormal" , "Weird, eerie" , "as quarks in certain hadrons" , "Unusual, odd" .)
