Man taken out of terminal has capacity to hold less than two pints (5)
I believe the answer is:
litre
'less than two pints' is the definition.
(I've seen this before)
'man taken out of terminal' is the wordplay.
'man' becomes 'lire' (I am not sure about this - if you are sure you should believe this answer much more).
'taken' indicates putting letters inside.
'of terminal' indicates one should take the final letters (I've seen 'terminal' mean this (terminal refers to the end)).
The final letter of 'out' is 't'.
'lire' placed around 't' is 'LITRE'.
'has capacity to hold' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for litre that I've seen before include "A pint or two" , "Nearly two pints" , "Fluid measure" , "non-imperial measure" , "It's equal to about 1.75 pints" .)
