Bug requiring computers, etc. to be taken out of service (5)
I believe the answer is:
lurgy
'bug' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'computers etc to be taken out of service' is the wordplay.
'computers etc' becomes 'IT' (short for Information Technology).
'to be taken out of' suggests deleting specific letters.
'service' becomes 'liturgy' (I've seen this before).
'liturgy' with 'it' removed is 'LURGY'.
'requiring' acts as a link.
Can you help me to learn more?
(Another definition for lurgy that I've seen is " Illness".)
