Pub ales - I smashed around 50. Believable? (9)
I believe the answer is:
plausible
'believable?' is the definition.
('plausible' can be similar in meaning to 'believable')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for plausible that I've seen before include "Apparently reasonable or probable" , "False but sounding true" , "Specious" , "easy to swallow" , "likely" .)
