See disruption when travelling appearing quite by chance (13)
I believe the answer is:
serendipitous
'quite by chance' is the definition.
The definition suggests an adjective which matches the answer.
'see disruption when travelling' is the wordplay.
'when travelling' indicates an anagram.
'see'+'disruption'='seedisruption'
'seedisruption' with letters rearranged gives 'SERENDIPITOUS'.
'appearing' is the link.
Can you help me to learn more?
(Other definitions for serendipitous that I've seen before include "Luckily" , "Found by chance" , "Fortunately" , "Lucky in making unexpected discoveries" , "Occurring by happy chance" .)
